I plan to crossfire my Asus EAH5670 1GB, at the moment i have a Thermaltake LitePower 500W power supply and a core 2 duo e6700. The Acer motherboard does not have 2 PCI-E slot, so i have this on Ebay which will buy. I had a look at the crossfire power supply requirements and it says 500W but i don't think my current is good enough, so would a Seventeam 650W power supply would power it up? The Acer case is a mid-atx, so the 2 cards would fit and they are single card slot. Would a my current processor bottleneck when there is 2 5670? If it does, i will get a core 2 quad q6600. Any one have any experience or know how well a Seventeam power supply performs? I know i am forking out money on something that is obsolete but i can not spend a great amount of money until when i am 18. Based from reviews of the 5670, it draws roughly about 200ish watts.

Parts i'm gonna buy:

Official TDP on a 5670 is 61 watts. 200 watts is the "estimated" total system draw. Even with an overclocked Q6600, total system draw will still be around the 300 watt mark with everything cranked (crossfired 5670s).

Seventeam tends to make good units.

As far a CPU bottlenecks, as long as they are clocked properly, it shouldn't be too much of a problem. Q6600s I think were available in a B3 and a G0 stepping, G0 clocked a lot better, and ran cooler. Something to look for. A Q6600 at 3.0 to 3.2 is still a happy setup. Some of the modern games are CPU crushers, but as far as bottlenecking a pair of 5670s, not likely.

For grins I hooked up the kill a watt to my E6750 (3.0ghz)/5670/550VX HTPC this morning. Total draw loaded.......195 watts at the wall.

My mum is cracking it at me now because of this. So you reckon that my E6700 won't bottleneck it?

It just depends on the game. GTA, Civilization are a couple that come to mind. Any game that requires a lot of physics calculations, flight sims. RPGs, RTS etc. Any game that you set the physics to "high" is a candidate as well.

Damn i play those games but mum has happily agreed to let me buy that core 2 quad. I am looking at very modern 775 Gigabyte motherboard which even has USB 3.0 which i have plans to buy. Also i am looking to buy a Coolermaster Hyper 212+ so i can overclock the core 2 quad to a higher clock speed.

http://www.pccasegear.com/index.php?main_page=product_info&cPath=186_218_1125&products_id=14540

It says i have to overclock the memory to 1333,so it can run at that speed, how do that?

Think about this a bit.

You are investing money into building a system that, except for memory, has absolutely no upgrade path. If you can get this stuff cheap/used, that is one thing, but you are still out money you could use on a fresh 1155 build. Sad truth is, even the low end Sandybridge dual core CPUs are going to be faster than a Q6600 once you get your CPU clocking sorted out. Just something to think about as I have found myself there investing money into an old socket instead of biting the bullet and upgrading to the latest tech.

As to the original question, you don't have to overclock the memory. You can still set dividers in the BIOS to run your memory at whatever speed you need. FSB and mem timing can be asynchronous, but you do get slightly better performance if they are matched. A Q6600 is a 1066 FSB CPU anyway, so any overclocks will still be under the 1333 speed of your memory.

If i bought the new Pentium Sandy Bridge processors and a new motherboard it would be still expensive. I just had a look at the benchmarks and the Core 2 Quad is actually faster then the new Pentium. Also you can not overclock it.

what are you intending to crossfire it with? another 5670? you didnt mention in your post, I assume you are. Keep in mind, that in any crossfire setup the first two letters have to match-so your card will crossfire with any card that starts with 56.

Yes with another Asus EAH5670 1GB but at the moment it doesn't look like this upgrade will go ahead due to my mum lecturing me about how this is waste of money. So maybe i can get a brand new build for christmas.
