I have taken some considerations from my previous thread and I just want to be absolutely sure before I pull the trigger on this. Ordering this Monday/Tuesday.
I have determined I need a new monitor as my current one has a max res of 1280x1024. The new monitor must be 1920x1200, fast response time, low input lag. I have plans to crossfire once the prices of 5850's drop. I want a quality supply so I would like to keep the corsair.
Some concerns I have are that I originally intended to go with 6gb of ram but dropped it 4gb to meet the budget and that the motherboards PCI slots are 2 x PCIe 2.0 x16 (single at x16 or dual at x8 / x8 mode). Basically I want to know if I should get a board that will act as dual x16 / x16 if I plan to crossfire or whether there would be a noticable difference between the two.
You don't need 6 GB of RAM for gaming. And it wouldn't be a good idea for the 1156 socket. The P55 uses dual channel RAM, which means the next step up from 4 GB is 8 GB. 6 GB is triple channel, which the 1366 socket uses.
There isn't a noticeable difference between 16x/16x and 8x/8x. And to get 16x/16x you need to build on an i7-920. So the cost would be around $200-250 more. The technical difference is only 4%, and is only really in play with Crossfired 5870s or 5970s.
