Im going to buy a samsung p2450 monitor, some how i doubt my 8800gts 640mb will be up to the task. Would a gtx 480 be a suitable replacement?
The 6950 is also a viable alternative, better than a 560 by some margin even at stock. They are also more efficient and do not have the power requirements of a 480.
