65nm AMD chips

[P373]

Im currently on a amd 3700 @ 2.7Ghz, socket 939 with 4x256mb ram. I want to go dual core for around £80. Cheapest i can find for a dual core 939 chip is £72 which is a 3800x2. If i did that i would sell my current ram and cpu for about £60 and pick up 2gb ddr400.

I was wondering is it worth going to am2 purely because of the price? I can sell my current cpu, ram and mobo to my dad for £90 so id have £170 to play with for am2.
65nm Amd 4000x2- £60 (another site)
DFI Infinity nF UltraII-M2/G- £41.11 (from ocuk)
2gb ddr677- around £70 (from a well known auction site)

I know most will scream that i should go to core2 but i really cant afford it. I'm looking for the cheapest way to go dual core and get best results. The question really is do the 65nm chips clock well enough so that its worth switching out all my major components?

I understand that i could go to core2 but i would probably only be able to afford 1gb of ram. Would it really be worth having a core2 chip with only 1gb ram as apposed to an amd dual core with 2gb? taking into account that this will be my last upgrade for a bit.

if intel r doing price cuts on the 22nd then i think i'll wait until then. If i can afford it ill go core2, if not i think ill stick with 939 if the am2 65nm chips rnt a greta deal better.

Ive decided im gonna wait till the 22nd and see what the Intel price drops bring but if i were to stay with 939 what do you think the best option would be? I will be overclocking and my board does a decent 300Mhz but is limited by the fact that it can only do 1.45v without a voltmod (its the asrcok dual-sata2).
The 2 chips ive been looking at are the opteron 165 and the 3800x2. Cheapest 165 ive seen is around the £100 mark whereas the 3800x2 is £72. I know the 165 "should" overclock further on lower voltage but its never guarentued, is it worth spending almost £30 more on a 165?
