Will £200 make a difference ?

[Dazstoke]

Hi,my first post here so be gentle with me
My current pc I built over 6 years ago and is as follows....
Case - can't remember the name and there's no name on it but it was highly recommended by all the reviews in it's day,has fans front and back and I'm thinking I can re-use this
Power supply - Tagan TG430-U15 430w....again hoping to re-use.
Motherboard - Asus A8N-SLi
CPU - AMD Athlon 64 3000
Graphics card - GeForce PCX6600GT
2Gb ram
Windows XP

It's getting a little long in the tooth and I'm hoping a motherboard and processor upgrade will make a big difference.

I've been recommended to go for something along the lines of a Asus P8H61-MX USB m/b,Intel Pentium G630 and 4GB Kingston hyperX ram and ditch the graphics card.

Will this be a big enough jump in performance to be noticeable or should I be going down another route ?
I don't play games and am not into overclocking.

There seems to be so much more choice out there these days and I'm a bit bewildered to be honest

Cheers

Here's my case with the side removed just for the photo

Yeh I'm aware I'll have to get new optical drives as mine are IDE but I have a brand new Sata HD that I never installed.

£200 is about all I really want to spend plus I'm probably going to install Windows 7 and that's going to be another 70 quid or so on top.
I'm definitely in the budget end lol
