New PC (HD5850 and i5-750)

So far I've found this:

Intel Core™ i7 Quad Processor i7-860

XFX Radeon HD 5770 1GB GDDR5

Corsair TX 750W PSU

ASUS P7P55D, P55, Socket-1156

How does it look?
It'll cost me 5127 dkk or 619 £. Seems like a quite good deal to me. Anything I should upgrade? Any bottlenecks? Is the motherboard even compatible with the rest?

You need to step it up son and get yourself a 5870. But why not wait for a Gtx 470? Only 2 more days.

Don't get an i7, get the i5 750. It's 95% of the performance for $80 less. Use the money you saved to get a 5850 instead of a 5770. Yes, the total CPU/GPU cost is a bit more than your original combo.. but it's much better for gaming, and an overall better value.
