Get the p5q. The less expensive chipsets overclock better. My friend got a 500$ striker like 1 1/2 years ago and ill he had was problems. It comes with soo many things that can break.
nvidia chipsets get nothing but bashed nowadays, although i've never personally had one... if your gonna get a second card, might a suggest an x48 motherboard? if your gonna stick with one card, maybe a p43 would be your best choice... i don't really know why anyone would pick a p45, if you can afford a striker extreme, you can surely afford an x48 right?...wait can you even FIND a striker extreme now?
