Firepro - to use or not to use?

[oxram]

My AMD Firepro v4900 card has just arrived and the first thing i see is a huge HP logo on the box
I open the box and am greeted by 'warranty void if not used on HP systems' in huge letters and a HP driver disk
I got the card for my work build and i did not realise i had bought the HP card. i don't really want to send it back (£40 instead of £130), does the HP version differ from AMD's?
Could I just use this in my non-HP build downloading drivers from AMD?

I think the OP says it cost him £40 instead of £130, thus the reluctance to return it?

yeah sorry about the confusion
It was on offer for £40 and I don't really want to spend over £130 on the same hardware having returned a perfectly suitable card for a third of the price
I was wanting to know if I would come up against any issues with either AMD's drivers on the HP card or the HP drivers on my non-HP system?
if it will work the same ill take the warranty loss for £90
