If you're building or upgrading a budget gaming rig, it'll be hard to ignore the GeForce GTX 650 and 660. Whether or not NVIDIA's new chipsets are worth the glance is another matter, and early reviews suggest that a sale depends on just which market you're in. The GTX 660, by far the darling of the review crowd, competes solidly against the Radeon HD 7850 by outrunning AMD's hardware in most situations while undercutting on the official price. Only a few have taken a look at the lower-end GTX 650, but it's not as much of a clear-cut purchasing decision -- the entry-level video often slots in between the performance of the Radeon HD 7750 and 7770 without the price edge of its bigger brother. Either card is much better value for the money than the GT 640, however, and looks to be a meaningful upgrade if you're trading up from equivalent prior-generation gear.
