One of the 280x's unfortunately died so I have a few options, budget is approx £200:
Simply replace the second 280x and remain at the same performance level. (approx £100-130)
Purchase a 7990 (about £70 more) to xfire with current 280x, and presumably a fair bit more tinkering (case has room for dual psu + adapter).
Or lastly change the GPU setup completely for single GPU, but potentially lose performance. 290, 290x or 970? Other options I have no found? The current working Asus 280x would need to be sold to increase the current budget though, which I am not keen on doing unless it would be worth it (near to the 280X xfire cheapest replacement at least)
Any opinions please, all are welcome.
