Better Motherboard and Graphics Card?

[cluthz]

450W will run a 2500k and 650TI, but it's gonna be noisy as it is gonna be using all it's power at load.
I would consider a 500w or more if it's a decent quality (80 plus bronze) or go 600w.

GeForce 560SE is Geforce 560 "SLow Edition" which is performing along the lines of an 550TI.

I've been happy with Gigabyte cards lately and I have Gigabyte GTX285 on it's 3rd year still!
My previous card was a MSI 9800GT OC, which died after 1.5 years, but I've heard they have shaped up their QC lately.

If you don't plan on crazy over clocking any Z77 board will do the job.

And finally, unless the 2500k is much cheaper than the 3570k, go with the 3570k.

You might wanna get an aftermarket cooler if you wanna OC, Coolermaster Hyper 212 is good for the price.
