I'm looking for a AMD Dual CPU motherboard that can cope with 2 660Ti's in SLI and 16 GB ram also it had to be under £300
You'll need Opteron processors, a workstation or server motherboard and ECC memory. That can't be done with your limited budget unless you buy older componnets, but then a current single generation CPU like the FX-8350 or i5-3570K would most likely be faster. Finding a workstation motherboard that supports SLI might prove difficult.
