Well in choosing between getting a performance laptop and a desktop with a netbook (or cheap equivalent) the desktop option is more and more tempting as I look into it and is incredible for the prices nowadays. I know these posts come up a lot but hey it's how someone who cares but isn't knowledgeable works.
My preliminary specs after researching for a while are a bit iffy, and any help would be great. Will add extra comments in parenthesis.
CPU - Intel i7-950 (it's only £20 more than the 930 and I like the slight stock clock bump)
Cooler - Noctua NH-D14 (AFAIK it fits with both MoBo's and the three RAM sticks will fit fine)
MoBo - Gigabyte GA-X58A-UD3R or Asus P6X58D-E (really not sure about the choice the Asus is £10 more and they seem to tie...)
RAM - Corsair XMS3 6GB (3x2G
DDR3 PC3-12800C9 1600MHz (could get some Patriot C8 RAM for £10 more or Corsair Dominator C8 RAM is £28 more)
Case - Coolermaster HAF 922 or Xigmatek Utgard (Xigmatek is £13 cheaper)
PSU - Corsair TX 850W (wanted to make sure there is plenty of headroom in W but I've read the TX can be loud)
HDD - Samsung Spin Point F3 SATAII 1TB 32MB Cache (going to use RAID 0 and would get an SSD boot drive in future)
ODD - Sony AD-5260S-0B 24x DVD+/-RW
GPU - EVGA, Asus or Zotac 580 GTX (chosen as prefer a single powerful card, not sure about brand as they're reference cards the EVGA has best warranty and support apparently and Asus is meant to be slightly OCed according to the Asus site so maybe it's a higher bin? Asus are apparently not great with support, RMA and drivers according to forum posts £20 difference across the 3 cards)
Monitor - Dell U2311H, Dell SP2309W, Samsung/Asus/BenQ etc. (Expanded below.)
The monitor is the hardest thing I've had to research and look for and it's proving to be a ridiculous task with an huge array of monitors all with similar specs and very very different reviews some reviews even contradicting leading me to think it's down to panel lottery and/or subjective reviewers. The laptop I was and still am half considering is the Alienware m17x R2 with it's 1920x1200 RGBLED screen, it's very sad to look at the prices of similar panels in monitors. I can max out at £300-350ish at a push but any less is great of course. The all round quality of the screen is important as I enjoy good colour and so on to play games, watch video but also be able to read a lot of text.
Apologies for the ultra long first post but it reduces the questions a helpful poster might have to be able to comment. Hope everything is there, apart from that lastly I wanted to know if there were any other things I would need such as better cables if some parts come with low quality ones, or thermal paste if the stuff that comes with the Noctua isn't great. Tools and other possible parts would be helpful too so I can tot up a full cost of what I'd need to get sorted. Any other useful forum links and tips on these parts would be invaluable, will also carry on searching around for more info. Additional things are of keyboard, webcam and some speakers but I've sorted all of that. Thanks for any replies!
