The RAM will run at a lower speed too. But it looks like you are not from the USA so pricings might make your choice the better decision. If you plan to run you RAM at greater than 800mhz, these higher clocked RAMs will work great, or you can get DDR2 800 RAM that uses micron ICs (G.Skill HZ's, crucial ballistix, buffalo firestix), these have been known to OC up to DDR2 1000 at spec.
You dont need it though, it just might be something you could consider.
I bowed down to ThunderChunky when he suggested the best overclocking ram.
I would get any of the 3 if I had the money. Any of them will o/c like mad.
You don't need to worry about "the mobo's 800mhz ram support" won't run higher speed ram. See that's what overclocking is for. Maximum stock is 800. You CAN turn it up all the way to specs like 1066 or even high if the ram can take the heat. Yes, you have to up the vdimm volt as well.
The only thing I'd change is the cpu cooler. It'll be loud at full speed. You have to go full speed to o/c or you'll limit your o/c. Freezer 7 Pro, Infinity, Ninja (see my sig), etc. are quieter ones.
Didn't realise this akhilles/thunderchunky, thanks. I've never looked into overclocking before so i'm not sure what's possible. dabs.ie and komplett.ie don't seem to stock the crucial memory but komplett.ie stocks the OCZ stuff but it brings my budget over the €2000 mark. Any suggestions from those 2 web sites that might suit my system better than what I specified?
Anybody got suggestion of a suitable PSU around €160.
