Have bought my pc parts, now need a card which will go nicely with my system

i5-2500k
Asus p867 le http://uk.asus.com/Motherboards/Intel_Socket_1155/P8P67_LE/
2x 4gb ddr3 kingston 1333mhz
Antec vsk2450 case - includes this power supply http://www.antec.com/Believe_it/product1.php?Type=NA==&id=Mjc4Mg==
1 HDD
1 DVD-rom
1 DVD-rw

Not going to overclock, everything will be stock.

Which card to get from the following pairs:

Nvidia GeForce Fermi GTX 460 1GB
or
ATI Radeon Barts HD 6850 1GB

ATI Radeon Juniper HD 5770 1GB
or
Nvidia GeForce Fermi GTS 450 1GB

and

Some issues im not sure of:

(1) the LE p8p67 mobo says (single at x16) will the cards i have listed work fine with my motherboard ?

1 x PCIe 2.0 x16 (blue, single at x16 mode)
1 x PCIe 2.0 x16 (black, at x4 mode, compatible with PCI Express x1 and x4 devices)
2
3 x PCI
* The PCIe x1 slots share the bandwidth with the PCIe x16_2 slot.
* Due to the CrossFireX™ limitation, DO NOT use the PCIe x1 slots when you install two CrossFireX™ graphics cards on both the PCIe x16 slots to set up a CrossFireX™ configuration.
* To disable the PCIe X1 slot, refer to the Onboard Devices Configuration section in the BIOS for details

(2) my main concern is will the power supply handle fine with the graphics cards i have listed (the link i have posted further up for the psu has readings if that helps), have tried various power supply calculators and they give different readings, most tend to show if i had a 6850 graphics card my psu voltage would atleast need to be 375w for my system but one has said 600w. So would like others opinions to get better idea

thanks

Why would you get an i5-2500K (including the "K" suffix) if you are not going to overclock?

I would choose 460 1GB over 6850 (or 6850 over 460 768MB), and 5770 over 450. I prefer the 5770 most.

(1) Yes all cards should work with the mobo.
(2) I have found the reviews from techpowerup most accurate regarding power consumptions of graphics cards. If you have doubt you could check there. I think it will be fine.

The card cost me a fiver more so thought it was the better choice. I have never overclocked so thought i wouldnt really bother right away, plus the mobo i have bought is the le version which limits overclocking. I bought everything on budget so i had to get everything and still have enough left over for a graphics card. But just having read an article where someone has accomplished to overclock their cpu to 4.5ghz, by overclocking manually on this board its good news, so i may do so after getting my card and if my power supply lets me.

ok so i have just changed cards on the power supply calculator from 6850 which gave my system a total of 371w to a gtx 460 card which boosts the power to 404w + one fan which i forgot to add (407w), so is there a great improvement from a 6850 to a 460 gtx as i have just looked at http://www.videocardbenchmark.net and the 6850 rates higher then the 460. thanks

If you overclock your CPU then you might want to use a graphics card with lower power consumption. Given that 460 1GB performs so close to 6850, the 6850 seems the best choice in such case. (techpowerup also says 6850 can save 25W-30W.)
 
460 would be my choice, but if you are worried about the power consumpion then a 6850 would be best.

As with overclocking with the LE, I had that and easily managed 4ghz
 
thanks for replying guys, gives me a better idea which to go for now
