Building a new intel rig, I need help with some decisions...

Ok here is the deal. I am tring to upgrade to a new machine. Ive had my AMD for almost 2 years and Im ready for some new stuff.

What I have now:

AMD 2500+ Barton OCed at 2.21Ghz
Asus A7N8X Deluxe REV2.0
2x512MB PC3200 Kingston Hyper-X
36GB Raptor 10K
AGP 8x ATi X800 Pro (retail ati card)

Here is what ive bought for the new rig so far:

Nvidia BFG 6800 Ultra OC 256MB PCI Express
74GB Raptor 10K


I also have this Dell Optiplex GX280 that is the new Mini tower with the BTX board. I bought a 3.6Ghz 560 Prescott for that and a 2x512MB DDR2 533Mhz kit of the Giel memory. I was thinking of putting my 36Gb raptor in this and selling it on ebay to get money to complete the new rig.

Now heres my problem:

Should I get a AMD 3800+ X2 and the Asus A8N Premium to put with my new stuff. Or should I keep this 3.6Ghz prescott and buy a ABIT Fatal1ty AA8XE board (any suggestions for another OCable board for the 3.6 would be appreciated!). Keep in mind here that I will be overclocking this on air to the max, I dont want to water cool. I hear the X2 3800 can go all the way to were it registers in windows as a 4800+ X2 on air alone(an $884 processor!)

Well; If u have the budget for the X2, u should buy that.
I think those CPUs r veryvery good!

A 3800+ (or lower) X2 will outperform that pressy. That's 100000000%

If you already have 560 and vid card, then all you need is DDR2 RAM and motherboard. The regular Abit AA8XE is cheaper than the Fatal1ty version and will O/C the same.
