I'm in the market for a new graphics card and have been looking to get a 770. Initially I was going to get an EVGA 770 superclocked 2gb with the acx cooling. However I have came across the gigabyte windforce 4gb 770, which is almost as fast as a msi lightning but has 4gb of memory. The reviews for the gigabyte seem pretty good, but I wasn't sure about their reputation and if someone would reccomend an asus or a 2gb msi lightning. I don't want to spend more than around $450. Thanks
