This is not a bad idea for a system (I paid for a Q6600 system in late 2007, specifically for Crysis, funnily enough). I do think it’s a bit limiting to use an 8800 series card in XP, as it restricts you to DirectX 9.0/Shader Model 3.0 (officially, not sure if there are work-arounds for that), but it’s a cool idea nonetheless. Any early DX10-supported game (World in Conflict, Bioshock, 2007/US version of Call of Juarez, etc.) won’t be able to be “maxed”, but I guess you’re mostly just missing out on some extra bells and whistles. The games won’t look bad in DX9.

As far as Crysis is concerned, there are some points worth considering before you decide to fully commit to making a PC tailored heavily for this game:

(1) The game is predominantly GPU-limited. I recently captured footage of me using a late 2003 system, with an Athlon 64 3200+ (early 2.0 GHz Clawhammer variant), a Radeon 9800XT and 2x512MBs of DDR400 2-3-3-6 RAM. The CPU does get a bit bogged down when lots of fighting occurs, but it’s really not the main reason Crysis is considered such a “machine killer”. Dual-core might help a little in some places, but this is only likely to become a problem in very crowded, very explosive and run-and-gun crazy situations, when lots of particles and smoke appears. Even if you put an 8800 GT/GTX in an early PCI-E board from 2004/2005 with a single-core CPU, this will help you out tremendously!

(2) This is related to the first point, but there are ways to make Crysis run significantly faster on slightly older GPUs than 8800 series without sacrificing visual quality all that much. The most demanding visual/GPU features in Crysis are also some of the most subjective ones. This includes most of the post-processing effects, such as motion blur (especially per-object!), sun shafts and color grading. I’ve managed to get very satisfactory performance on a Radeon X1900 XT (512MB) by disabling these effects at 1024x768 pixels. This is only the tip of the iceberg, however, as you can choose to tweak further by disabling stuff like shadow filtering, lowering shadow mapping resolution a little, lowering level-of-detail (LOD) for terrain objects, and so on, with little impact to the beauty of the game!

(3) Yes, you can force Very High graphical settings in Crysis on Windows XP/DX9, but you can’t do so without some visual flaws (at least not in version 1.0 of the game)! These flaws don’t appear everywhere, mind you, and I only remember the second level/map having any distracting artefacts (blurry arms on hostage, super-blocky canopy shadows during the river section later in the level) occurring because of this. Still, worth keeping in mind. It’s not as if you really NEED to max out every setting in DX9 to make Crysis look sweet, but if you consider doing so, you have been warned. The final fight is pretty miserable on the performance side in DX10, on the flip side, so there is that advantage at least! Crysis is a DX9 game at heart, after all.

Look, I’m not trying to discourage you from making a 2007 machine, just not necessarily PREDOMINANTLY for this game. Crysis was a one-of-a-kind tech-wonder, it was one of the poster-children for DX10 at the time, yes, but it was still designed to scale to vastly different configurations and very much still be enjoyed on slightly older graphics cards! I’ve had the privilege of playing it on a 2003 GPU (with some beautification tweaks), 2005 GPU, 2006 GPU and 2007 GPU, each time still admiring its high environmental interactivity and tropical atmosphere, and each time finding joy in the experience of playing it!

I guess what I’m trying to say is something along the lines of “don’t let this one big tree block the rest of the forest from your view”. There are some technically demanding games from 2006 too, some not that far behind what Crysis did. This includes Call of Juarez, Company of Heroes, Neverwinter Nights 2, Gothic 3, and more, that I think are just as worthy of being played as Crysis. I’ve had some of the best times in my life in mid-to-late 2000s games using an early Athlon 64 X2 setup, and I don’t think striving for having a bunch of extra CPU cores is really worth for most (if any) game from the 2000s, in my experience thus far.

Make a CPU and memory platform that conforms to as many games you hold dear as possible, then let the choice of GPU solve for any exceptional cases!
All that blabbering aside, it’s a very cool project and just go with what you feel is right for you! Don’t let my opinions and observations discourage you.

Thank you for your detailed input, I appreciate it 😀

Don't worry, I'm not building a PC just for Crysis, as that isn't really a main goal. I can understand how the way I talked about it would give that impression though, so that's on me 😜 I simply mentioned it as a fun curiosity to check out for a realistic idea of how it would handle on a high-end PC of that time. I appreciate your tips and information on the game though! I'll definitely keep them in mind if I decide to benchmark the game on the system.

My main purpose of using it would be to enjoy all sorts of XP games with the best hardware of that time, since I personally like seeing an authentic system not play old games at 400+ FPS at all times. It's quite a refreshing and different experience I enjoy when in the mood for it 😀

I might check out those other games you mentioned as well, they seem fun and interesting.

I hear you! Just keeping having fun exploring all sorts of WinXP titles from that timeframe with whatever hardware does the job for ya!

I used to have a functioning Core 2 Extreme dual-core machine, until the board got ruined by me. Don’t have my first Q6600 PC anymore (the part selection was terrible anyway). I’ve considered making a new one, but I think I might possibly settle on making an XP-and-Vista 32-bit dual-boot/-drive solution for my Athlon 64 X2 machine instead, and just deal with swapping between GPUs when needed. Saves me more space, haha!

Corsair HX620 or OCZ 700GXSSLI

I'd say don't bother with either of these as you're not gaining anything by buying a 20 year old PSU

In terms of performance, reliability and safety, yes, a nearly 20 year old PSU will not do many wonders for any build. But remember the goal here is authenticity and being period-correct, and even if putting in a newer Corsair is a wiser idea, it just misses the point for me. It would bother me a lot while using it 😜

I'll only resort to a brand new PSU if I absolutely cannot find any proper old PSU to use, but it would kind of suck to compromise like that.

I have systems with far older power supplies still in active use. There shouldn’t be any problem any time soon with these older Corsair units, especially when not in constant operation.

By the way, Lime, I spent a bunch of time some year ago thinking about and researching 2006/2007 cooling solutions for Core 2 processors, right before I ruined my 975X board (sob). There is a great review from back in the day that tested all sorts of LGA775 coolers, named the “ LGA 775 CPU Cooler Mega Test”, by HEXUS. Very worthwhile read!

I’ll put up a link that starts off at page 6, right before the test kicks off: https://m.hexus.net/tech/reviews/cooling/8757 … ga-test/?page=6

I also read up on the original Thermaltake Big Typhoon, which is supposed to be an excellent choice too, and ended up buying one. Unfortunately, I slipped with my hand when trying to install the damn thing, which resulted in me being Core 2-less.

I had a slightly newer build in 2008 with Core 2 Quad QX9650 @3.8Ghz and dual 8800GTS 512amb in SLI. Even that struggled with Crysis at max settings (at 1920x1200 at the time) . It was very playable, just not super-smooth. I forget what the actual framerate was now. I still have this machine in the garage. I have intended to restore it for years. Haha.
