XFX GF 8800GTX 575M 768MB DDR3 Dual DVI TV SLI
 

The 8800GTX is the fastest single graphics card on the market today bar none. The performance with two of them just flat outperforms everything on the market and then some when it works. Two of these cards working together in SLI flat out allows gamers to play games at Ultra High Resolution gaming like 2048x1536 or 2560x1600 with little trouble as long as the rest of the system including the PSU matches up.
