I would take the F3 HD over the others, except that the WD has a 5 year warranty.
This looks like a nice build.
I prefer modular over non modular PSU's, but CPU magazine just matched the Corsair 750W vs the XFX 750 (among others) and gave the XFX 3 1/2 outta 5 and the corsair unit 4.5.
Food for thought, I like the Antec 750 neo myself. http://www.newegg.com/Product/Product.aspx?Item=N82E168...
@ Silvune - That's great thanks. I'm not planning to SLI or crossfire atm, but it's nice to have the option!
@buzznut - Any reason over choosing the F3 over the barracuda? I must confess, I didn't see a lot of difference myself except the price!
That's interesting about the PSUs. I'm unsure which one to pick now, the Antec one is quite expensive compared to the other two - but if it's significantly more effective I guess I can't argue. Are you suggesting I get 750W instead of 650W by the way?.. or is this just based on your own build?
A system with an OCed i7-920/930 and two 460s (or two 5850s - they have the same TDP) won't even use 500 watts under full furmark load which is much more stressful than a game, so a PSU that can deliver 650watts is the sweet spot for such a system.
Go for which ever harddrive you want, they're both pretty much as fast as each other.
I had a barracuda (320GB 7200.10) that failed on me after one year and I lost confidence in the brand. I hear good things about the 7200.12, but I don't recommend barracudas as I believe the samsung drives offer superior performance.
I must admit I am not 100% positive where the barracuda sits in relative performance between these three.
I have never had a WD drive fail on me, until recently when a 500GB green drive went belly up. So speed and reliability is why I am recommending the Samsung drives now.
I am sorry if I have confused the issue for you. Silvune's recommendations are solid, after researching a bit the XFX looks like a solid PSU. The main complaints of the XFX are stiff cables for routing and a fan that is not so quiet.
The OCZ model is very quiet, but has shorter cables than the competition.
The antecs have cables that are a good length, even for bottom mounting.
These days you want as much power available on the 12V rails as possible. The Corsair TX and XFX have over 600 watts available on their 12V rails. The Antec Earthwatts only has ~530 on it's, and the ModXstream only has ~505. So I don't think they are appropriate choices if you want to be able to add a second graphics card, as they are likely to be making more noise, heat, etc. Obviously they would be fine for one graphics card. Also they don't have enough hardwired PCI-E connectors, so would have to resort to molex adapters - which I'm not a fan of and would prefer to avoid.
@ buzznut - Do you have a link to the comparison between the Corsair and XFX you mentioned earlier? I'm curious as to why this magazine rated the Corsair better than the XFX, because all the info I have tells me that the XFX is the better PSU.
Which (OP) is why I think the XFX is a much better deal at £7 cheaper than the TX, and highly superior and worth the extra cost over the Antec Earthwatts 650 and the OCZ ModXStream Pro 600W.
Unfortunately I know next to nothing about wireless cards.
hmm its a hard choice... but also the most important one I've heard. I think I would probably replace/ upgrade a card rather than pci it if that makes any difference? I don't use games on the computers, but usually maya and after effects are the most graphics intensive things I do
