Help upgrading my current PC

[Superkleb]

Greetings Techspot forum people. I am wanting to upgrade my PC, but without having to replace my motherboard, so I am just wondering what is the best hardware I can actually get for my make and model. I feel a bit lazy asking, but when it comes to actual hardware Im a bit clueless and more than a bit paranoid of getting something wrong All help would be much appreciated as I know you probably have better stuff to do, but Im sure there are a tonne of people out there to whom stuff like this is second nature Here goes...

My MOBO is a Gigabyte [FONT=Verdana]GA-EG41MF-US2H (Link- [/FONT]http://www.gigabyte.com/products/product-page.aspx?pid=3469#ov)
*Some other specs
Current CPU- Celeron E3200 dual, overclocked to about 3.2
OS- Win XP 32 bit (yeah, I know)
GPU- GeForce 8800GTX
Memory- 2GB (Because of 32 bit OS)
PSU- 650W
This PC was built from scratch by an old friend of mine especially for me. I am based in the UK (England, Lancashire) and we usually buy most of our parts from http://www.scan.co.uk/ who have a store in Bolton, which is not far from us. I really dont want to replace the motherboard and therefore buy a WHOLE new system, so any help regarding any one piece of hardware would be great

If any more info is needed, I will try my best. I used CPU-Z to get most of it.
Thanks in advance!
Kyle.
Edit: I use my PC primarily for gaming.

Most important question: what's your budget?

If you're gaming the GPU will be the best upgrade, but recommendations all depend on your budget.

If you want you can get a Core 2 Duo/Quad to replace your Celeron, but they're legacy products now and you'll have to buy one off eBay. It's probably advisable not to upgrade your CPU/mobo/RAM and save up for a new combo.

Hey, thanks for the reply. Hmm, as far as budget is concerned Im not entirely sure. Im off to Sweden beginning of august for a week but after that money shouldnt be too big a problem so all recommendations are welcome.
Does my MoBo support quad cores then? Was under the impression it didnt If so, then that is good news.
Ill also be upgrading my OS obviously so I can add more than 2 GB RAM.

You can get a Socket 775 Quad-core CPU but you're better off saving for a new combo as Slh suggested.

Well if you have the money then just get an i5 2500K, mobo and some DDR3 RAM. A Core 2 Quad and DDR2 RAM have very inflated prices because they are legacy. Just had a quick look online and a new C2Q Q8400 is the same price as an i5 2500K.

Hey guys, thanks for the reply again and sorry I didnt reply so quickly (work has me busy). Cool, its good that I can chuck a quad core in there. That should make it a load better. Like you said though slh28, the legacy prices are high, but I should be able to manage it after I get back from holiday. Found an i5 2500 k for around £150 also, so I dunno... Some good info there guys, it is much appreciated. Ill keep checking back here too.
