Hey all, I'm new to the forums, and I just ordered an MSI 8800GT OC from newegg.com, this one to be exact. http://www.newegg.com/Product/Product.aspx?nm_mc=AFC-SlickDeals&cm_mmc=AFC-SlickDeals-_-NA-_-NA-_-NA&Item=N82E16814127329 I was wondering what kind of performance I would be getting, and how much of an upgrade that is over an 8500GT. More importantly, I was wondering if this power supply was adequate, and an overall good choice... http://www.newegg.com/Product/Product.aspx?Item=N82E16817371007 It's an Antec 500 Watt PSU. Is the brand any good? Thanks in advance for all your help, and I look forward to posting here more often!
