First things first, i need another HDD as i currently only have 30GB left on my current. Price range about £70 and 1TB size if possible.

and some new RAM, currently on 32bit XP so will only register 3.2ish of 4gig (correct?) but im looking to upgrade soon to W7 and will get 64bit so might as well get 4gig now yes? price, £50 ?

not the best tech guy so if the prices are to low for what im asking for, do say. Thanks for any help!

Do you also happen to know what speed (for example; 800Mhz) and from which manufacturer your RAM is?

[gazzthompson]

400mhz max bandwidth according to cpuz

Cossair 2 X 2gb Kit. 4gb at 800Mhz is enough for most things these days, isn't much of an e-peen swinger anymore these days though. But this kit is cheap and does the job very well.

63 pounds, but worth it - click me

Link is just so you know the product you will be able to find cheaper, being in australia its a pain in the *** to look for parts in other places, hard to find a good deal since none of my shops are over there.
