Windows 7 says it's up to date, but nVidia website says otherwise. Downloading the newest ones now and will see if that helps.
Checking the cable has revealed that the DVI-D cable that came with it is only single link, not dual. If drivers don't work i'll buy a DVI-D Dual link cable tomorrow.
I have been needing a new gfx for a while but didn't get one because my 19" monitor could already handle everything. This has given me an excuse to go out and get a new gfx card, do you think a 4890 will suffice?
Updating drivers didn't do a thing, still can't get above 1200x800 without having my screen flashing. It will just keep flashing until the "revert back to previous configuration" timer expires and puts the resolution back.
If you are a hardcore gamer and want all graphics settings maxed out, then I would suggest something more powerful than a HD 4890. Otherwise you should be okay. See below for benchmarks notice the very low frames per second for Crysis Warhead, then again it is an exception, not the rule.
The HD 4890 sells for just under $200 if you can find one. The HD 5850 starts at $290. AMD is expected to release the HD 5830 relatively soon (whenever that is) which is supposed to bridge the gap between the HD 5770 (roughly $170 and not recommend for 2560 x 1600) and the HD 5850. Best guess on price is probably $225 - $250 based on current prices.
