Actionn,
Yes I use it for games, but I'm into racing sims. NASCAR, Evo 4x4, etc. I couldn't tell ya what fps I'd get for CS, Quake, Payne, RCW, etc. I run 1024x768, 32bit, high detail w/all but 'tire tracks'/'particles' on & avg 35+fps in my games. Not killer, but for a MX card & 500 Celeron/320 PC-133 it is working fine for now.
I recently dl'd a new demo: "Pro Race Driver" by Codemasters. Cranked the graphics setting to full & opened it up. Beautiful graphics. Very realistic renderings. Detailed cars & scenery. 10fps! Yep, it started at 10 fps. I had to turn things down due to the 'lag' between the js & the pic. This is a DX8 game. It isn't 'out' yet. It 'worked' my system to the max. 'New Generation' game.
For PCI, all we have is the MX cards. For todays games: they do a decent job, IMHO. The price can't be beat either! :grinthumb
FWIW: I haven't had a single problem w/my VisionTek GF2MX400 64mb PCI. I read comments about 'problems' with the cards, but I haven't experienced any. I must stress that I do have a cooling fan blowing across the HS equipt PCI card.
Enjoy your card,
