im running a 780i, Q9450 2.66, 2GB DDR2. ive needed to upgrade my graphics card for quite a while now and was looking for suggestions/advice on which to go with. ive narrowed it down to either a 9800GX2, a 9800GTX+, or a pair of 9600GT's/8800gt's. ill be using crysis as a test and i am at a loss...
