need help with PSU

[nattydreds]

well im building a new gaming pc and these are the specs ive chosen:

c2d e4300
8800gts 320mb
Gigabyte DS3 (rev3.3)
2gb g.skill ddr2-800
160gb WD HDD
silverstone tj04 case

now its come down to 2 psu choices, both from silverstone. i do plan on overclocking up to 3ghz and need to know which psu will be best for me, keeping in mind the budget.

silverstone element 500W

silverstone olympia 650W
http://www.playtech.co.nz/product.php?action=showdetail&id=2980

the olympia is almost $100 more than the element and i want to know if i do get the cheaper element, whether or not it will be able 2 support my overclocking or whether its worth the extra $ for the olympia. thnx.

ok thnx alot, i think for now ill just stick with the element. you say all new video cards will be using 8pin pci-e connectors, does this include the 8800gts?
