Hi Peeps,
I've not been on the forums for a while but I enjoy helping people out! Just kicking around and I thought i'd have a little to say. I've been shopping at YoYoTech for a long time and I think they give really sound advice
Time for my 2 cents (or pence)
Your rig looks great, no mater what the final combination of components you end up with, you'll be happy
I would go for Dominators over Reapers. There are quite a few incompatibilities with OCZ which are less documented. Corsairs go through far better testing and compatibility tests (they really can afford it). This is what I've learnt from people in the industry so I think its credible. Just look how OCZ still dont show the rated voltage on most of their memory, where as corsair have been doing so for AGES. Not very helpful to us DIY'ers eh? I dont want to always have to check their website for voltages although im sure it increases their traffic lots. OCZ do seem pretty good for returns though..
If your not building the system then Yoyo will have real problems running 4x sticks at 1066. They will either have to slow the memory timings or have to drop the Mhz down just to get the system stable... Which you really dont want
In terms of PSU's I think coolermaster PSU's are second only to Corsair. When you go higher than 620W then definately go with coolermaster as they are still modular and offer really good efficiency. Just read some reviews if your unsure, they get great reviews just like Corsair
OCZ PSU's were briefly mentioned by staffsMike but they are quite simply terrible. Noisy, cheaply made and just a waste of good money! Just pick one up and you'll see how light it is (lack of components or cheap components? Or both!?) I have heard real horror stories from OCZ's PSU blowing entire systems.... Again some research will show this
As staffsMike has also said.. a 600W truepower PSU will run 2x 8800 GTX's but thats running it at the limits of its design. Theres no way I'd do that. I prefer to have at least 100W-200W to play with on top of the possible peak usage. Its much more likely that a PSU will go pop if its always running at full power over say an 800W with quite a bit of headroom. Of course your not going to be running it at full load all the time but im just saying... Do you want to risk data loss / lots of parts being RMA'd just because you didnt go for a higher power PSU?
Either way Im sure you'll end up one happy customer
