Probably not...I'm probably gonna get a computer within the next 9 months so yeah.
I just did a Far Cry 2 benchmark in DX10 mode at 1280x1024x75, all ultra high/high/on settings:
Total Frames: 4213, Total Time: 284.06s
Average Framerate: 14.83
Max. Framerate: 29.94 (Frame:92, 3.41s)
Min. Framerate: 6.51 (Frame:3894, 254.75s)
That kind of sucks...well, compared to my 2600PRO, it's better, I guess...just not as good as I thought it would be before I ordered the 4850...at all.
