Best upgrade for £100ish?

Please could anyone suggest a good upgrade for this, around or less than £100 with VAT.

Greatly appreciated, I want to be able to record ingame video without halving my FPS

Other spec:

And would you expect it to make a decent difference to my system? Thanks for the advice so far.

Also, could someone confirm compatibility please? for example, bus: PCI-E 2.0. I dont know if my asus mobo is v2.0? How can I check, or am I being simple

Thanks

Either will also work fine in your motherboard - whilst they state PCI-E 2.0 and your motherboard is PCI-E 1.0, there will be no compatibility issues.

Good to know, ta. Will there be any performance issues? Would I be losing out at all?

Theres a good chance I have now placed this order

Thanks very much for all your help So long as the bank doesn't shaft me again like they did my last order (blocked the "suspicious" purchase 3 times... ) it should be with me next week

Super!

For £100 or there abouts this is your best bet imo
