Hey there. I am curerently in the market for a new gaming rig. I am looking to run FSX with good FPS and Crysis with good FPS.
I have a 22" Asus widescreen monitor.
I have come to the following specs:
Intel Core 2 Quad Q9550
PowerColor ATI HD4870 512MB GDDR5
Arctic Cooling Freezer 7 Pro
Asus P5Q Pro
Corsair Dominator XMS2 4GB (2x2GB) DDR2 PC8500 C5
Samsung 500GB SATAII
NOX Urano 600W 12cm SLI
NZXT Apollo Black
that looks like a really good set up.
my only concern is the power supply i would at least go with a 750 watt now and days you never know what your going to need to sli or Xfire in your case. i would also try and get a partitioned power supply. so you don't have a ton of unused cables hanging about. that leads to bad air flow henceforth high temps.
you have a top of the line gaming rig as far as Im concerned.
By partitioned PSU he means a Modular PSU and he's right, try to get a brand name, PSUs are by far the most important part. If I were you I'd get a Q6600 instead of the Q9550 and OC it. Other than that, looks good.
PC Power and Cooling (no modular ) and Corsair have some nice PSU offerings. The Corsair 750w is not modular, the 1000w is modular.
If you are planning on Crossfiring a second GPU, you might want to consider an X48 MOBO. It would give you an extra performance gain (although some here argue not a big difference) over the P45 MOBO. Good X48 MOBO's are Asus Rampage or P5E Deluxe ($$$ to $$).
For PSU cooler I like the ...
