So I have chosen all of the parts for my build and this is the final bit that I am debating between, I can get an Asus 280x for £245 and a Asus 780 for £399, The game that I am going to play the most (that needs such power) is a heavily modded version of Skyrim - 2k Textures/An ENB, most likely RealVision and Enhanced Lighting & FX etc. Obviously both cards have 3Gb Vram so that is not really an Issue especially with me playing at 1080p. In the ideal world I would like to achieve a constant 60FPS. Do you think the 780 is worth the £150 more than the 280x?
Also I intend on keeping the build/card for 2 years.
780 is the higher performing card, but you should consider the 280x if your main purpose is to play games like Skyrim at 1080p. This is because Skyrim mods seems to prefer AMD drivers. The 780 is still a little overkill for games at 1080p, unless you're trying to max out the 1% of games that are truly demanding e.g Crysis 3.
