New PC, Critique Build

[tzvii]

I am going to college this year and need a new computer.
I am an engineering major, I plan on using this for schoolwork and gaming.

I put together a list today of parts that look good, not quite sure yet though.

Mobo: UD4 Newegg.com - GIGABYTE GA-P67A-UD4-B3 LGA 1155 Intel P67 SATA 6Gb/s USB 3.0 ATX Intel Motherboard
GPU: GTX 570 Newegg.com - EVGA 012-P3-1571-KR GeForce GTX 570 HD w/Display-Port (Fermi) 1280MB 320-bit GDDR5 PCI Express 2.0 x16 HDCP Ready SLI Support Video Card
PSU: TX 850 Newegg.com - CORSAIR Enthusiast Series TX850 V2 850W ATX12V v2.31/ EPS12V v2.92 80 PLUS BRONZE Certified Active PFC High Performance Power Supply
CPU: i5 2500k Newegg.com - Intel Core i5-2500K Sandy Bridge 3.3GHz (3.7GHz Turbo Boost) 4 x 256KB L2 Cache 6MB L3 Cache LGA 1155 95W Quad-Core Desktop Processor BX80623I52500K
RAM: 8GB DDR3 1600 Newegg.com - CORSAIR XMS3 8GB (4 x 2GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800) Desktop Memory Model CMX8GX3M4A1600C9
HDD: C300 64 GB SSD Newegg.com - Crucial RealSSD C300 CTFDDAC064MAG-1G1 2.5" 64GB SATA III MLC Internal Solid State Drive (SSD)
Case: CM 60 II Newegg.com - COOLER MASTER RC-692-KKN3 CM690 II Basic Black Steel ATX Mid Tower Computer Case
I have another 1TB HD from my old PC I will be reusing.

I'm trying to keep the cost around where it is at, $1200. That being said, if there are any improvements that could be made for not much more money, please let me know.
I chose the 2500k processor thinking that it is not much different than the 2600k for my purposes, I do not intend to do any major encoding.. Are there any other reasons it may be worth the extra costs?

Gaming wise, what games do you plan on running, at what settings? And what programs do you use for school? These can determine what CPU you should go with, and if you need the 570 or not.

I wouldn't bother with the 2600k...the extra cores don't make a huge difference in my opinion...it's not like cutting off a minute or two to finish encoding anything is worth $100.

You can save $10 (well, $18 with shipping) if you go with this motherboard which is very similar and even a little better for the value:
Newegg.com - MSI P67A-GD65 (B3) LGA 1155 Intel P67 SATA 6Gb/s USB 3.0 ATX Intel Motherboard

If you wanted to cut the costs a little more and you aren't planning on getting a second 570 for SLI in the near future you could get a 750w psu or even a 650w psu being that EVGA's 570 only needs

Minimum 550W or greater system power supply (with a minimum 12V current rating of 38A)

Newegg.com - CORSAIR Enthusiast Series CMPSU-650TX 650W ATX12V / EPS12V SLI Ready CrossFire Ready 80 PLUS Certified Active PFC Compatible with Core i7 Power Supply
Newegg.com - CORSAIR Enthusiast Series TX650 V2 650W ATX12V v2.31/ EPS12V v2.92 80 PLUS BRONZE Certified Active PFC High Performance Power Supply
These are both from corsair. I've read some good and some bad things about the newest TX series, so I don't know if you'll want that or not, but it's still an option. That overall should save you around $40. You can use the extra $60 for a better looking case (if that matters to you), a better SSD, or get an optical drive which I noticed was missing...if you aren't using an old one.
