Missing 2d hardware acceleration of the video card (no blitter).

This won't matter in vanilla doom, right? How about in dos source ports of doom? Or vanilla doom running in windows, for that matter?

Afaik, no DOS game ever made use of 2d hardware acceleration. This was really a Windows-only thing.

Any vlb card will solve this, right? I'm willing to buy any of these (well apart from the 2mb one):

512 is plenty for dos but isn't much for Windows either especially 9x. depending on what resolution you want.

Just to confirm you do have a VLB slot right? Good ISA card will also work as long as its not biased on a crappy/outdated chip.
VLB was never budget so you its at least decent, however some are better then others especially when it comes to gaming, and may actually be slower then a ISA card.
(we are talking a few fps though, nothing I personally would worry about)

I do have VLB. Just wondering, what would this ISA card be like? The date on it is quite old: http://www.old.vgamuseum.info/component/conte … s-f82c450b.html

That's an old chipset. I'd go for a later Cirrus Logic VLB card (f.ex. GD5428) if you want a good price/performance ratio for GUI acceleration.
The CPU is also utilized in GUI rendering, so upgrading that might help too.

P3 rig:
- ASUS CUSL2 w/ i815 BIOS Tweaker
- Pin-modded Tualatin 1.26GHz 512kB @ 1358MHz
- 512MB SDRAM @ 143MHz CL2
- PCI SATA w/ 128GB Samsung SSD
- ATi Radeon 9600 XT 128MB (APG 4x, AGP clk @ ~71MHz)
- Creative Sound Blaster Live!

I'm definitely going to the get the cirrus logic one, but it has to come all the way from Ukraine so I was looking for another one that was available locally in the meantime (no vlb ones locally). The cpu it's going into is a 486-100, so not much in the way of upgrade options (I want to keep it as a 100 anyway)

DX4-100 is already pretty good for a 486. I'd go for a GD5429 VLB if you can find one for cheap. Being patient pays off when it comes to getting a nice retro rig.
Finding one that is maxed out at 2MB VRAM (all chips present) is a nice bonus.

I'm just going to get both since the isa one is cheap and could be used in another system, but how can I tell whether it has blitter?

I don't know of a specific way, but for Cirrus Logic it seems that the hardware BitBLT routine is present in GD5426 and later according to Wikipedia. I'd ultimately go for a VLB (VESA Local Bus), should be much faster.
