The compatibility between vanilla and Ti are the same. There is a performance difference, but your games are so old a GT740 would be enough for most if not all of them.

Thank you very much for your help! In your opinion, I shouldn't be concerned about setting antialiasing to the maximum, considering my graphics card only has 1 GB of VRAM?

When most of these games came out no graphics card had more than 256MB. The industry only moved to sell graphics cards with 512MB with the high-end models of Radeon R500 (X1000) and G70 (Radeon 7000) series in late 2005. 1GB as an option, and not a standard came a good 2 years later.

GTX 750 with ivy bridge i7 will make short work of all those games performance-wise but compatibility (driver is too new) may be an issue for less known titles released around year 2000.

For XP, may be worth disabling HT in BIOS, so it runs only 1 thread per core, as XP does not have core vs HT thread aware scheduling

Given how overpowered the CPU is for the games in question, I doubt it'll make much difference.
but given it's such a low risk/low effort change OP can see if it makes any difference easy enough if they wish

The era for the games listed would have them generally max out at using a two cores. The XBox 360 was released in 2005 and had three cores, while the 2006 PlayStation 3 had one big core and seven smaller almost GPU shader like computer units. It really wasn't until 2008/9 when development started utilizing the full PS3 that games started be more multithreaded. There's pretty much zero reason to go with an i7 over an i5. Though and i3 with disabled hyperthreading so it was just a dual core is also more than enough for almost any XP game.

Thank you so much for all the responses!

I know the choice of components might seem a bit odd when compared to the final goal of the build, so here’s some context:
Originally, I wanted to create a kind of “Windows XP Ultimate” system, built specifically to play a handful of childhood games — but with all graphics settings maxed out.

The original GPU was an EVGA GTX 980 Ti, which unfortunately started having issues, especially with crashing in solid colors while playing Fable: The Lost Chapters. Sometimes the crashes would freeze the whole system until a restart, and other times I'd get a Windows pop-up saying the NVIDIA driver had stopped working. I ran a stress test and it showed tens of thousands of VRAM errors. I believe this was due to the high temperatures where I live and a poor cooling setup.

That was a tough hit — not only because I had paid a lot for that GPU, but also because parts are hard to find where I live, my tech knowledge is limited, and my budget isn't the biggest.
So, a bit shaken by the experience, I decided to prioritize reliability over raw performance. I just wanted something that could run those few games on max settings, at a stable 75fps to match my 75Hz monitor, without giving me headaches.

After dealing with a lot of compatibility issues and trial-and-error with different parts, I’ve reached a point where I just want the system to work — and to last — so I can simply enjoy playing.

In your opinion, did it make sense for me to go with the GTX 750? I got it pretty cheap (even though it was a bit of an accidental purchase), but I’m open to upgrading(read downgrading to something that makes more sense) in the future if there’s a better option worth considering.

Does it lets you play all of the games you want at maxed out settings for your display? If so, what benefit would you get from a more powerful GPU? You are running hardware that is up to a decade newer than the games so it's more powerful that the fastest hardware when those games were released, but sips power.

The top end GPUs of a series are normally red lined. They are sucking down power and pumping out a bunch of heat to hit their performance levels. This can cause extra wear on the parts causing them to die more quickly. A card that's using 1/3rd of the power could potentially last longer.

So, in the end. If the card is playing everything you want at the settings and performance you want. What more are you looking to achieve?

The top end of the series be it CPU, GPU, or something else will often be much more expensive because people are conditioned to what the best of the best. But a step down could be 10-15% less performance but cost orders of magnitude less. When doing a build, also come up with a target on what you want the build to achieve. Then figure out what parts will match your goals without breaking the bank, while having the best chance to not be limping along on its last legs being a ticking time bomb waiting to die on you.

Thanks for helping me out!
I think what I was trying to express wasn’t about wanting more GPU power, but actually the opposite — I’m looking to scale down.

At first, the goal was to build the most powerful XP-era machine I could, as if money weren’t an issue back then. But after losing the GPU (which I honestly think was my fault — it was working perfectly and could run anything at first), my priorities changed. Now, I just want a system that can run all those games smoothly, without giving me headaches.

My question was more like:
"Can I go even lower in performance, still keep all the games running at max quality with a solid 75fps minimum, and reduce power consumption even more — all without running into bottlenecks or other issues?"

Gotcha, IMO no. You are at somewhat of a crazy sweet spot. The GTX 750 is rated at 55W, go a generation back and you are at 65W for a GTX 650. The GTX 550ti is 116W and GTS 450 is 106W. While a few percentage points (6-7%) more powerful card like the GTX 470 is 4x the power at 215W.

You normally have to go newer to get more performance for less power, but the GTX 950 is a 90W card.

If you didn't already, go into your BIOS and disable hyperthreading. You might also want to think about disabling two of the cores so you'll have only two cores running since as discussed above most XP games don't really scale beyond a dual core and your ivybridge is way more CPU power than XP era games will need. And since you have an unlocked K processor, maybe thing about limiting the multiplier to underclock it a little so it will use less power when boosting.

I think the low hanging fruit here is CPU.
Games listed don’t benefit from quad core and they won’t be bottlenecked by much cooler model (like i3-3220T)

I’d speculate you may even be well with a Celeron. And sell 3770K for profit to an overclocker if money is the issue.
It’s only in late 00s games after Bioshock you may start seeing CPU bottleneck.
