atitool is a great vid card stress test. It gets my vid card like 7c hotter than anything else I throw at it. I've tried q4, hl2, fear, doom3, ut2k4 for hours and nothing I play gets it near as hot as that damn lil cube in atitool. If it don't artifact under atitool, it won't under a game.
Not a bad card. Unfortunately the last quad will NOT unlock, 12pipe is all you get. It is still slower than a flashed c3d x800gto for $154. I think at ~ $140 it would be a sweet deal.
If you want $300 card powering your 17" monitor, go for it. I see guys in $2000 civics w/ $3000 rims too, whatever floats your boat. :) You will definately get some sweet AF & AA in games.
Given that you are on a ~$30 17" monitor, a 7800GT is overkill.
Go $180 c3d GTO + $125 ebay 21" trinitron = $305 The winnah!!
A 21" trintron + c3d GTO will give you a WAY better gaming experience than a 7800GT on a POS 17" monitor IMHO.
Just an ole core r423, x800pro core, running on a ole .13 a64 w/ poor case cooling. My c3d gto gets 7200 3dmark05 w/ stock cooling. :)
