Advice on core PC components.

[Cat]

So my current PC recently died. After some poking, it turned out that the motherboard had fried, taking my RAM and GPU with it. Partial upgrade time.

I'm keeping a lot of stuff from my current build (HDDs,PSU,Case,Moniters etc), so only really need to buy the core Board/Ram/CPU/GPU as an upgrade. Budget isn't really an issue, the systems I've been pricing out come in the £600-£700 range, but I could comfortably spend at least double that (but don't want to waste a huge amount on a stupidly powerful high end system).

I'm generally not going to be overclocking, as my room gets hot enough at the best of times.

Heres the parts I've been thinking of. Any input appreciated.

CPU - Intel i5 760.
I see no need to spend a fortune on a 1366 board/6 core CPU, as the performance increase is apparantly marginal at best. Going the i5 760 seems to be a powerful chip, and I can pick one up for a little less than £150.

Motherboard - Gigabyte P55A-UD3
The H57/H55 chipset series seem to be designed for integrated GPU, so those were out. Going for a lower end model of the P55 chipset, since the only difference between the UD3 and the UD4/UD7 models seems to be their support for multiple GPUs. Since I will not be running more than a single card, this won't be an issue. Is there any other difference between these boards that I've missed? I know a solid MB is important, so don't mind shelling out for quality, but at the same time don't want to throw away £50-£80 on something that won't benefit me at all.

RAM -
As I have an 1156 board, RAM will be dual channel. Anything more than 4GB seems overkill, so i'll be sticking with that. A little unsure about frequency on RAM however. I know that the CPU itself has a memory controller which states how fast your RAM will run by default. The i5 760 lists memory speeds as 1366/1066/800, however the motherboard spec states it can handle ram with frequency 2200/1600/1366etc. Which takes predecence? Debating between this and this. Second set of memory is has faster frequency, slightly higher latency and a little more expensive.

GPU - GTX 470
Very solid card, will do pretty much everthing I want it to do, not much else to say on this really. Read nothing but good things about it, so unless theres anything else out there which gives equal bang for less buck?

Sidenote - PSU Antec True Power Trio 650W
650W PSU with 3x12V rails, each with 19amps. I'm thinking this should be easily enough for the new hardware?

Cheers for any advice.

Might recommend a higher PSU so you can SLI later for an easy upgrade. As is, it is probably sufficient atm

If you still play XI, go ATI. nVidia's driver support team is low manned and focuses on new games/don't properly beta test/don't actually have a copy of XI to beta test with. There's been a 9 month driver issue for XI where nVidia's newer cards take a massive dump on your FPS whenever it has to render a player sprite. Dual flagship SLI get under 5~ fps with just 8~ players on screen no weather or shadows. It might get fixed soon but if it bugs out again who knows how long you'll have to wait.

5850 or 5870 either or I would recommend.

after playing XI for so long I steer clear of Nvidia

I belive the i7 had a price reduction recently with intel getting ready for the sandy bridge, so I'd look into that.

I know you said you don't want to overclock, but you can literally just change the base clock on an i7/5 and get a 30-40% overclock with no voltage increase and marginal temperature increase.

If you go with the i7, I've been using the ASUS P6T deluxe motherboard and it's rock solid and has all the options you'll need.

I've also had bad experiences with nvidia. My last build was built around their products and I was completely underwhelmed with the perforamance and reliability. ATI all the way for me. The 5870 is a nice card.
