I bet you money you can get 2000 linked and synced with 4 gigs of memory, your quad will do 4+ easy dude, i seen them hitting 4.5 and more, the 8x multi is your key, 8x500 4.0 processor, 2000 ram, try 4 gigs and see, i will post my settings you can try them, 8gigs of ram is asking alot, you may have to settle for 4 gigs, at 2000, or return your ram and get 8 gigs of 1800 ram, i will post my settings, we see what happens.
