Hi, this is the first time I've tried to make my own computer. My budget is about £950 for the computer and for the most part I've got everything picked out and just need a bit of advice on some things and just a general check to see if everything will work together.
What I've got so far:
Antec 300 Case (£41.99)
OCZ GameXtreme 850w (£84.99) OR Corsair Memory 750w TX series ATX (£97.95)
Samsung 1TB Spinpoint F3 7400rpm 32MB (£58.82)
Samsung SH-S223 22X DVD±RW DL & RAM SATA - OEM Black (£14.99)
ASUS P7P55D-E P55 Socket 1156 (£121.36)
Intel Core i5-750 Quad Core 2.66GHz 8MB (£162.45)
XFX ATI Radeon 5850 HD 1GB PCI-Express 2.1 x16 HDMI DX11 (£250.43)
Windows 7 Home Premium (£82.98)
As for the RAM, initially I was looking at 3x2Gb of 1333Mhz Ballistix RAM but was told this was a bad idea considering the motherboard is dual channel, so I started looking at 2x2Gb of 1600Mhz and came up with either:
Corsair 4GB (2x2GB) DDR3 1600MHz/PC3-12800 XMS3 i5 Memory Kit CL9(9-9-9-24) 1.65V - Ebuyer
G-Skill 4GB (2x2GB) DDR3 1600MHz/PC3-12800 Ripjaw Memory Kit CL7(7-8-7-24) 1.65V - Ebuyer
4GB kit (2GBx2), Ballistix 240-pin DIMM, DDR3 PC3-12800 upgrades for ASUS P7P55D-E Motherboard, CT1147964 from Crucial.com
They're all around the same price (~£100), I'm pretty sure the G-Skill set is the better of the three but looks absolutely disgusting, followed by the Ballistix and then the corsair set, so barring the horrible looks I'd be inclined to go with the G-skill set (Maybe I'm wrong though?). However confirmation of compatibility with the motherboard would be nice (I've noticed the motherboard has a 1.5v RAM slot compared to the majority of performance RAM being 1.65v??)
With regards to the PSU, there's two contenders at the moment, the corsair 750w and the cheaper OCZ 850w, the corsair is more expensive but is it worth spending the extra for it, or is the OCZ comparable in quality?
The other thing I was wondering about was the difference between the various brands of GPU's, at the moment I've gone with the XFX 5850, as it was one of the cheaper options, there was also the option of the stock Sapphire 5850 which was £10 dearer and their various overclocked versions which can cost upto £300 and the Asus 5850 which was also ~£10 dearer. Is there a brand preference? Is it worth spending the extra £10 for the stock Sapphire or Asus compared to the cheaper XFX?
So what do you guys think? Can you see anything drastically wrong or possibly spot some parts that won't really work together properly? Also, if could recommend any better parts for similar prices that I should take a look at, that would be nice!
