Problem is the exchange rate and shortages. A lot of cards have increased by over a £100 so to swap now would mean paying up to £100 more.
If all prices were the same then it wouldnt be an issue. I had a G1 Gaming on pre order at £530 and a EVGA FTW at £560. If I wanted to buy either today then both would cost an extra £130-£140. All those cards you listed are "lessor" cards and the cheapest is £90 more.
Yea people can swap to sometimes a lesser card then their pre order and pay over £100 for the privilege or just wait it out.
Great that Gibbo has allowed certain long pre-order people to swap at no cost but those are the exceptions.
The palit was just the cheapest one without a reference cooler, the zotac has a 5 year warranty versus 2 years for the others, but how often are you replacing cards - 2 years should be enough, the gainward would be my choice from reviews I've seen, they seem great.
Please define lesser and what these cards lack, and does a better card really justify a 3 month+ wait? And how much longer is this guy going to have to wait for his card?
