Good GPU for the cash, no problems. Just dont forget to overclock.
750W of off brand power isnt at all good. Your system will need 600W at most and you will want a better name on your PSU as its better quality. If anything in your PC breaks, you had better hope not the PSU, as thatl fry the rest of the build. Corsair, Seasonic and Silverstone are the three big names in PSU's, followed by OCZ, Thermaltake and Coolermaster. So that's your ladder of quality assurance. http://www.newegg.com/Product/Product.aspx?Item=N82E168...
