Im getting a new graphics card, I now have a NVIDIA 7800 GFX (256 version) and im running it on a dell WPF2407 24 inch LCD at a res. of 1900x1280 (or whatever the number is close to that res). My question is this: I read the reviews on this site and I want to get the 8800 GTS (620 version). Would this be sufficient to run graphic-intensive games (Oblivion, LOTRO, etc.) with all the higher settings? The card I have now struggles. Thanks.
