Apevia PSUs are O.k, but I wouldn't go with them for a power hungry system. Go with something from FSP, Corsair, or Antec instead. The raptor is a good performance drive, but you may find the storage space lacking if you don't have a secondary drive. If you're only going to have one hard drive I would say go with a WD cavalier black, such as the 1TB model, instead. Having a USB gaming headset kind of bypasses the onboard sound and uses up more CPU cycles. If that's what you want to use them you may want to disable the onboard sound to save some clock cycles if that devices processes sound on it's own. Personally I would spend money on more ram or a faster CPU before investing so much in the peripherals since you can get those latter and just start off with some cheaper decent input devices. I'd also go with a DVD burner instead of just a CD burner, or at least a combo driver, considering more and more games are being released strictly on DVD. You're spending more on your mouse than what it would cost for a decent DVD burner.
I'm going to end up buying the Razer Megalodon when it becomes available for purchase, and I decided to get 8 gigs of G.SKILL PI Black 4GB (2 x 2GB) 240-Pin DDR2 SDRAM DDR2 800 (PC2 6400) Dual Channel Kit Desktop Memory Model F2-6400CL4D-4GBPI-B - Retail.
I decided on the
GIGABYTE GA-EP45-UD3P LGA 775 Intel P45 ATX Intel Motherboard - Retail mobo,
CORSAIR CMPSU-750TX 750W ATX12V / EPS12V SLI Ready CrossFire Ready 80 PLUS Certified Active PFC Power Supply - Retail power supply.
I also replaced the cd burner,I mistook it for a dvd burner.
Will 750 watts be enough?
Also should I stick with the Q9550 or upgrade to a i7?
Also, if you're trying to save some money, ditch the HDD and get a Western Digital 640 GB HDD.
It's up to you on the i7 or 9550 - If I had the money and was building today, I'd got i7, but you will also have to take into account that the motherboard will set you back $250-300, CPU will be another $300, and RAM is all DDR3, so it'll set you back quite a bit too.
You may want to check out a 4870 1GB if you are sticking with the P45, since it will allow you to crossfire.
I'd go with the i7 920 instead of the 940. I just can't see how the price difference is justified. The 920 is an excellent overclocker. I've personally seen a 920 do 4.2GHz on air.
If you're going to go with 4870 1GB cards in crossfire, you might want to consider the 4870x2 instead. You'll have the option of adding another one in the future that way (even though I don't think you'd need to). Another argument for the 4870x2 is that the motherboard you chose goes to 8x speed in crossfire according to its specs.
