100% agree where you're coming from. Been there myself. It's how my Pentium build turned into an i5 :lol
Don't discount used cards too. This is a good value 660 Ti, the 3GB model. Not sure if the warranty is transferable though http://www.ebay.co.uk/itm/KFA2-Nvid...raphics_Video_TV_Cards_TW&hash=item4adda85c26
Edit - Seems warranty isn't transferable, shame http://www.kfa2.com/warranty.shtml
They're a lesser brand so can't charge a premium like others.
Although warranties in UK are not usually transferable, as long as you have the invoice they will sort it out.
As KFA say
Warranty coverage requires proof of purchase documentation evidencing the date of purchase (sales receipt or invoice), place of purchase, purchase price, item number or ID, and original packaging and accessories.
So even if you arent the original owner, but the person gives you these details, then it should be fine, since the company wont ask to prove the details are yours, they will onyl validate the information you provide.
If buying from ebay, just ask if the seller can provide that first.
