Unsure of components

[Sepheh]

Basically I know this forum gets flooded with spec threads but I have got a fair amount of money coming towards me and decided to spend about 2000-2500 on a new computer. Want it to be the best I can afford for this money, already made my mind up on a lot of the components and unless you guys can suggest a lot better then please do. I am a massive fan of asus for anything and want a full tower case. Unsure about what is better at the moment intel or amd so there is no preference I just want the better out of the both of them.

So in short I basically want suggestions on the best motherboard processor and graphics card(s). Always had intel in the past but honestly no longer have a preference.

I will be using my computer for a lot of gaming and would love to experience the benefits of two graphics card in sli so top of the range would be great because i want it as future proofed as possible.

As for the operating system, is it about time i moved forwards and embraced Vista over windows xp?

Anyway my current choices:

Lian-Li PC V2000B PLUS Black Aluminium Full-Tower (No PSU)

LG L1900J Fantasy 19" LCD Monitor - Black/Red x 2

Enermax Galaxy 1000W EGX1000EWL ATX2.2 Modular PSU

Logitech Z-5500 THX® Certified 5.1 505 Watts Speakers - Retail

Auzentech X-Meridian 7.1 Soundcard

Soundgraph iMON Ultra Bay - Black

LiteON DH-20A1P-45C 20x DVD±RW x12 Ram Dual Layer DVD-Writer (Black)

Western Digital Raptor X 150GB WD1500AHFD 10,000RPM SATA 16MB Cache

PC2-8500 1066MHz SLI-Ready Edition Dual Channel DDR2 (OCZ2N1066SR2GK) OCZ 2GB (2 x 1GB)

Thermalright Ultra-120 Extreme (Socket AM2/LGA775) Heatsink

Microsoft Windows Vista Home Premium 64-Bit Edition DVD

The main list of components I am happy with, I have 320gb of storage from my current machine going into the new one so the raptor i went for purely for access speed. As for the monitors I like having dual monitors as opposed to one widescreen, just personal preference. The powersupply was to be just as powerful as possible as i have a fair bit of hardware running off my current rig and the 480w i have now is seemingly struggling.

So SLI isnt necessary, thats good to know because that cuts down the cost and does mean i can spend more money on a better graphics card. The information about the quad core is what i was after. Honestly when it comes to processors and motherboards i am very out of date. I have an ASUS P4C800-E motherboard at the moment and would preferably like to stick with ASUS because I have never had a problem with all my ASUS products (3 motherboards and 3 graphics cards so far).

As for overclocking, yes I will be tinkering with this but not to much, so if you could pair some good overclocking RAM in there then feel free. The information so far has been awesome!

Thanks for the replies guys!
