ok, so looking into things so far (and already having to change the budget - factoring in the sale of the old processor and Mobo on Ebay!) the spec I am looking at is as follows:
AMD Phenom X4 9650 2.3GHz Socket AM2+ 2MB L3 Cache £116.07
Sapphire PURE CrossFireX PC-AM2RX780 770 Socket AM2+ 8 channel audio ATX Motherboard £79.42
OCZ 4GB (2X2gb) ddr2 1066MHz/PC2-8500 Platinum Memory CL5 £58.87
Sapphire HD 4830 1GB GDDR3 Dual DVI HDTV Out PCI-E Graphics Card £104.99
Antec TruePower Trio 650W PSU - With 3x 12v Rails and 120mm Fan £75.84
All totalling £435.19 (ouch! Already £90 over budget )
I thought I would probably need to beef up the PSU, so that it would be able to cope with things like a second GPU in the future - would this kind of size seem about right?
Anyway, any comments on the spec, or suggested improvements?
Not sure this is really a very good budget build for that price.
Let me show you a build for £400 max, give me a minute because I allready have most of the parts I put together for a friend the other day.
