Ready to buy but need a PSU

[bushmins]

I got my finger buzzing to buy now. Quick before i change my mind!

My spec
Win 7 (soon to be)
Q8200 @ 2.8
4 gig of DDR2 PC-26400C4 800MHz Ultra low latency duel channel
1 HDD
1 DVD
560GTX (probably)

What PSU will power this lot? The cheapest, nothing over kill. I know my spec might not be able to full use the 560GTX, but its there for further upgrades.

Thanks.

If i had the money i would. The above setup is what i have to play with, just need something to make sure i have enough to power it.
