Hi,
I hope someone can provide some help and will be grateful for any responses.
I just bought a GTX660 to replace my Radeon 6950 (not a huge upgrade but a swap was needed for various reasons). The problem is I am getting much worse frames in Crysis3 etc than on the Radeon. I have also seen repeated driver crashes where the screen goes black then Windows throws up a notification that the card became unresponsive and has been relaunched. These only occur outside of games, most frequently when just browsing in Chrome and can occur less than a minute apart.
Having tried a refresh of Windows (8, x64) to no avail I thought I would run 3DMark11 on both cards. The results are quite shocking:
These were carried out on the following rig with bios at stock and having cleaned all drivers with driversweeper each time and then installing the latest respective driver:
I7 920
3x4gb corsair vengeance triple channel ram
P6T motherboard
650w PSU (I forget right now but a "proper" one)
The results are as follows:
GTX660
Graphics Score 1971
Physics Score 5288
Combined Score 1750
6950
Graphics Score 4938
Physics Score 5854
Combined Score 4811
The exact model of the new card is: Gigabyte GTX 660 Windforce OC 2 GB. It is placed in the same PCI 16x slot as the Radeon.
Any help greatly appreciated, though I fear for the card's life.
