Best upgrade option?

[The_Vindicator]

I'm looking to upgrade my current system, used mainly for games and multimedia, my current specs are as follows:

Intel P4 2.8 @ 3.4
Asus P4C800 Deluxe
1024Mb OCZ PC4000
Radeon X800XL AGP @ 430/1100
2x80GB SATA raid 0
2x40GB ATA
Enermax 350W PSU

I have a budget of around £400/$700, with no brand loyalties to Intel or AMD so each is fair game.

The only thing I wont be able to upgrade is the X800XL due to the tight budget, so I will require a system with an AGP slot.

Any suggestions would be well recieved

TIA Vindi

updated with more info..

update,

After a bit of looking around i've decided on going AMD, due to cost/performance.

Would the Asus A8V Rev.2 Deluxe VIA K8T800 Pro motherboard be a good buy, its socket 939 and has AGP, but its been out over a year. Any other recomendations?
Also would my OCZ gold PC4000 memory be compatible with this board?

The CPU I was thinking of was maybe an AMD Athlon 64 3500+ Venice, maybe a bit higher if I have a bit spare cash at the end of it..

sell ur video card. get a pci-e

dfi ultra -d + venice 3000-3200 and oc it with ur ram

I say that you should either:

sell the CPU and the video card and
get a 3.4Ghz Prescott and a X850XT AGP

or

sell video card, mobo, and CPU and
get a 3500+, any SLI mobo, and 6800GT

i agree with Shmuckety on his second recomendation

 

[MaMMa]

why spend extra money on a 3500 when u can get a 3000 or a 3200 and oc a lot better then the 3500s?

Use the extra money u saved from that and throw it towards a better vga card

how can you people afford to upgrade so frequently? I still have a 1900+ and a 9700 pro
