^^ Buy a nVidia GTX 560 Ti PERIOD mate you can game, Fermi supports Tessellations (so its win-win) you can game as well as use the nVidia optimized Plug-Ins for MAYA and PhotoShop no sweat bruv.
Although if you want to game and don't really care about nVidia CUDA bling then an AMD HD 6950 1GB will fit the bill, squeeze a better frame-rate than the 560 Ti and can handle MAYA and other softwares with ease.
