Heyyo,
Heh, too true aboot D3. Doesn't run very smooth but it ran.
Now, UT2k7, it'll run I bet onna 6600gt, heck, I bet a 9800 pro would run it on lowest settings. This game's just started to get underway, it'll obviously run bad. Once they start polishing the Unreal Warfare 3 engine we'll start hearing how it runs great on budget setups. Budget setups of next year will probably be a 6600gt or 6800 ultra. By budget (well to me for vidcards) I mean under $200 CAD.
At first I thought UT2k4 would crawl on my computer, but hey, it runs very good, I'm quite satisfied with its preformance actually. The average budget gamer upgrages his computer every 1-2 years. so yeah, by then I'm sure people will have good comp rigs.
