Today's a sad day for Windows XP fans. This marks the end of a long road, but rather than view it as a somber occasion, use it as opportunity to build that modern day gaming PC you always wanted. Thanks to advances in technology since XP's glory days, you don't have to take out a second mortgage to build a respectable system. To get started, have a look at today's top deal for an Asus GeForce GTX 660 Graphics Card for $170 with free shipping (normally $200 - use coupon code: [EMCPFPG29]; additional $20 mail-in-rebate). Based on Nvidia's Kepler architecture, this card sports 960 CUDA cores, 2GB of GDDR5 memory on a 192-bit bus, and is factory overclocked (1020MHz core/1085MHz boost). Topping it off is a custom cooling soluiton that Asus claims is 20 percent cooler and 3 times quieter than reference.
