Hello all. This is my first build and I am trying to put together a system ~1000$. I already have most of the peripherals for the computer and I just need the rig itself. I do some light gaming (RTS type games, HL2, Spore?) and I am an engineering student and I run a lot of engineering programs MathCad, Matlab, C, Fortran etc. I also I tend to multitask alot. Finally I was hoping to dabble in overclocking and I was hoping this set up would give me the chance. Thanks for your time.
The P45 mobos are just now being released and although I have not seen reviews or prices on them yet, I think you should wait a few days for more info on them. The P45 will give you PCIe 2.0 which will match your video card and may provide more functionality if you want to upgrade to a faster card later.
I think you can get better than the XClio for that price. Try for a Cooler Master RC-690, and buy extra fans with the money you save. The XClio looks pretty, but I honestly think you will be happier with a Cooler Master in the long run.
I would personally get a Gigabyte EP35-DS3L and save a few more bucks. It is one of the best boards on the market right now, and priced at less than $100. You could grab an 8800 GTS 512mb with the money you save.
You will not need a 750w PSU for that setup. A Corsair 650 TX should do you just fine.
As far as overclocking, I would get a Xigmatek HDT-S1283 instead of the ACF7 CPU cooler. Make sure to get a tube of Arctic Cooling MX-2 thermal compound along with it.
That looks like a mess, sorry. Try this. I kept the bigger PS, because last computer I had the PS was too small once I added 4 HDs and I don't want any headaches. Also I went with a more $$ mobo in hopes that I may be able to upgrade a little in the future.
The X48-DS4 looks to be a great motherboard. But don't choose it based on a future upgrade option. The next CPUs to be released will use a different socket. I actually think the ABIT IP35 Pro or EP35-DS3L are a better choice unless you're thinking of a dual GPU Crossfire setup.
The Corsair 650TX will save you $30 and still give you a lot of upgrading & overclocking power. I would have recommended the 550VX but the 650TX is only $10 more.
With the money you've saved so far I'm suggesting you spend $55 more on the video card and get the Evga 8800GTS (G92) just on the chance you might want to use the Evga StepUp program and grab one of the GT260's sometime in the next 90 days (after you order).
