GFX swap help....

Hey there

i've decided to sell my pc..... cos i want to change my life for good :)

One of my mates is interested in my Scan XFX Geforce 7800GT PCI-E 256MB - its about 9 months old...

and he wants to swap it with an... Ati X850xt PCI-E 256MB thats abotu 1 year old...

now i want money with the swap cos its less old- how much do you reckon i should charge with the X850XT?

If you're planning on selling the PC for good, can't your mate just sell his old card on ebay?

nope cos he has the 850XT in his pc at the mo ;)
