HD4850x2 RMA replacement quandry

My Saphire 1GB HD4850x2 recently died a death and a replacement has been approved by Scan. They aren't expecting any in stock for a while and asked if anything else on their site was suitable. I can't see anything that offers the same 'bang for buck', so if anyone could offer any suggestions...

I would look at an HD4890 OC or GTX275 or a pair of HD4850 1gb cards if you have a Crossfire capable motherboard.

Ask them if they mind if you wait for a week or 2........
New ATI cards innit :)
