Hello guys, i recently ordered a hd5970, but i am now worried about how much my cpu will hold it back. Should i cancel the order and get a hd5870 to reduce bottleneck?. My cpu is a Intel Core 2 Quad Q9300@ 2.5ghz which has been overclocked too 3.8ghz and has had no problems with my current HD4870x2 setup. Should i upgrade to i5/i7 build or will the quad do its job for now?. Thanks guys.
