So my logic is, go with this mobo and in future I can add another HD5850 (2x x16 PCIe 2.0), another 6 GB Ram (total 12 GB, 6 slots), and intel's new i9 six core's will support sock 1366. Will most likely need a PSU upgrade too.
What do you guys think about using my old case and psu?
I believe this adds to <1700 which I am happy with, any comments would be greatly appreciated.
Personaly I dont want to go to 1366 yet as no one seems to be putting a lot of development into it as yet - they will go all out when i9's come though. Old case will be fine, providing it has good cooling. as for the PSU, I really like corsair PSU's so you might as well upgrade.
Other than that, it will do what you need it to do just fine. Waste of money? Meh...
According to the reviews I've checked the TP3-650 is a decent performer. It does not have enough PCI-E connectors for more than one 5850. So you would have to use the molex adapters if you didn't want to change PSU. It would be nice if you could see into the future to see if getting a quality power supply for your needs will be cheaper now or in the future when you buy the second card.
The i7 930 has been released, which is the replacement for the now discontinued i7 920, if you are interested, it is not too much more expensive and apparently it overclocks better.
