I'm tempted to hugely flame EVGA here, but it can't be denied that they are really great for US customers. If you live in the EU, however, forget about it completely. EU customers get treated like dirt by EVGA.
Some things that aren't made clear about step up when people buy EVGA cards:
-Don't forget that there is often a long wait for stepping up. An example for this is EU customers who wanted to step up to the GT when it came out, haven't moved more that 3 places in the queue since then. Hence people will be stepping up to very obsolete cards.
-The 'cost' of the card that you step up to will be more than you can find retail. In the US, you might pay, maybe $20 more. In EU, maybe $80 more.
-There have been numerous problems with Step up customers receiving old (RMA) cards as replacements. I reckon EVGA try and sneakily slip their excess RMA cards in there, but thats just my (admittedly very stunted) view. This is a worryingly regular occurance.
-When you successfully step up in the US, with wonderful customer service, low cost and quick turnaround, you make us EUers miserable!
Not that I'm bitter, you understand!
All the same, some considerations that you wouldn't at first consider, but do blunt the advantage of the experience somewhat.
