You just need one of these, available at your local BestBuy.

Oh I hear you there. I know I got lucky, and for a budget buy that 8800GTS does its job. The 512 is the edition to go with no doubt due to its remanufactured design and pixel pushing force. A higher texture fill rate for games that load background textures off LOD view, are definitely going to see a difference there. I think an Ultra is more suited for fps games due to its memory power house but for streamline games that 8800GTS 512 edition might get n extra 6fps -1tic.

Edit: LAWL at the jackass above me. Go to the link provided and read the stats man. Its redesign model only fills texture rates on the fly faster. It has no other advantages and still lacks in memory bandwidth, which is important for high quality special effects, flares, specular, dynamic lighting, dynamic shading, and pixel seperation.
