Best Air/Water cooler for overclocking a 3700+ SD, under £70?

[azza21]

Hello i'm going to build a new PC which i intend to overclock the CPU, which should be fun as i'm a total newbie to the overclocking game. I am going to buy an retail 3700+ SD, problem is i have no idea what Air/water cooler would give me the best overclocking results. I've seen a few that interest me (Gigabyte 3D Galaxy Liquid Cooling System) but me being a newbie to it all i need some expert advice from you lot, I do not want to spend over £70 on a cooler but i would like to achieve decent overclocking results i.e. 2.7/2.8ghz.
If you guys think i need to change an item please tell me what motherboard etc...would be better suited

My intended purchases:

AMD Athlon 64 3700+ San Diego 1MB
Corsair 2GB DDR XMS3200C2PT TwinX (2x1GB)
Asus A8R32-MVP Deluxe Crossfire (Socket 939) PCI-Express Motherboard "Cos of the xpress 3200 support"
Sapphire ATI Radeon X1900 XT-X 512MB GDDR3 AVIVO TV-Out/Dual DVI "Can only afford one atm"
Gigabyte Aurora Case
Unsure about what PSU to buy yet?

I already have a dvd-r/cdr combi, WD Raptor 74gb hd and audigy 2 zs sound card, which i will use.

Ha ha everyones saying different Air Coolers. I guess all the above are good at overcloking the amd 3700+. But is there not any air coolers that is renowned as being the best cooler for overclocking when it comes to an amd 3700+? Also what do you peeps think to the motherboard is it a good overclocking mboard?
What PSU should i get with them sort of specs and overclocking in mind?
