I use a 20" CRT which maxes out on 1600x1200. The funny thing is, some games run perfectley on my machine: like HL2-i set everything to max and i can honestly say i never got below 30 fps. Games like FEAR work well too, but at max settings and max res skips just a tad bit from 10-25 fps. To be honest with you, im more or less content with the game preformance, the only reason im writing this is that im afraid that oblivion will ravage my pc if i try to put it up to 1600x1200 res. (My motherboard was fried by a static shock, so now im getting it replaced so i cant play oblivion to actually find out what it is like) If anybody has any experience with how good oblvion is optimized, and what kind of resources it needs, please tell me, im really worried bout it.
P.S. I run low latency 2x512 OCZ Ram (not sure if its DDR or DDR2) asus a8n sli premium, manchester 4000+ X2 and one 300 gig drive.
