With top end GPU's running in the $500 price range, stepped down models that offer great performance are popular. The PNY GTX-470 retails for around $350 and features a Limited Lifetime Warranty yet offers most of the performance of the GTX-480 so for price conscious enthusiasts might be a better choice.With generations of GPU's flying by picking up one GTX-470 now and another after the next generation launches is an attractive option. One GTX-470 is almost overkill but for those demanding top performance at a less than top price GTX-470 SLI is probably the best option we've seen.
