Hi All, I am considering my next buying option for my pc. Reason being I want to improve my video set up. I am considering a couple of options. 1. Selling my Zalman cooled 7800 GT and going for a X1800 XT - i know I am going to take a hit on my 7800.. just wondering if it is best doing it now. 2. Changing my Mono, buying another 7800 GT and going for an SLI set up. Any thoughts?
