Why not get the Core i7 920? You can save a lot of cash, and you can overclock it for better performance than the i7 940. You could get a sweet cooler for your LGA 1366 and still have money for a good set of RAM. The money you save also help fund a X58 motherboard purchase. In other words, Core i7 920 is the sweet spot.
Have an idea on what your total budget is? Hard core gaming machine or general purpose computer system?
Anything carried over from your old system?
Need suggestion on keyboard/mouse, monitor and speakers?
What about OS? Need an OS? You should look for a 64-bit to get most out of 6GB and even 3GB. The max RAM a 32-bit OS could use with a 2GB frame buffer (on 4870X2) would be 2GB. It's an OS limitation, so go 64-bit to alleviate that problem all together.
yea, def getting a 64 OS. THe system is going to be a gaming rig / graphics rig for 3d animations and video editing. My overall budget is 3K but I need everything, motherboards, case, power supply, ram, HD, monitor. I'm basically buying a new computer to replace my laptop, which is about 2 yrs old.
I'd try shooting for one of the big boy monitors. the 30" 25x16 resolution. with a 4870x2 card anything less might not do the card true justice. I think with this budget it should be considerd. Otherwise like WR2 noted there are a lot of areas that the current setup suggests could be more cost effective. By allowing this it'd drop your price range down a lot.
Need a blue ray burner? Or is a dvd burner good enough?
