Upgrade Spec Please

[shortone]

Hi all,
I am itching for a new upgrade but on a limited budget.
My currents system is
AMD 3700 san diego 939 oc to 2600
1gig Kingston Hyperx 3200 ram ( 2x 512)
Epox nvraid 4 mobo
2x 72gb raptors in raid 0
1 x 300gb seagate drive
Leadtek 7800gt 256mb
Antec Sonata Case
Hiper 580w PSU

I have around £400 to spend and ideally only want to replace the Mobo/CPU/ram
I will be selling the other kit on to a friend. Is it worth swapping the GT card for an ATI 1950 ? I would like the option for SLI/Xfire in the future.

This system will be used for video editing using Avid Xpress and for playing games such as Oblivion. I ideally would like to keep the raptors as raid 0.

I was thinking of an E3600 as the cpu but thats as far as I have got.

As always any help will be gratefully received.

Cheers

Shorty

Thanks Guys, so its worth sticking with the 7800 gt ?

mm seems that the Asus A8N32-SLi Deluxe nForce4 SLi X16 (Socket 939) PCI-Express Motherboard is AMD not INtel can you recommend an SLI mobo to go with the conroe, it needs to have sata raid.

Bump for the morning crowd.

Can anyone recommend a raid/sli conroe mobo ?

Thanks for that I hadn't considered a separate raid card but the economics seem to make sense.
