I've decided that it was about time I bought myself a new PC - my old one could just about handle RTW and BI and medium graphics settings and normal / large units, but can no longer handle any new games - the weak link in the system being the processor. But it has done well, as I bought it back in 2000.
Having had a browse of the internet, I was thinking of
this - but with the Dual Core E6700, 2GB RAM, plus no speakers / monitor (already have these) and it came out at around £1450.
My budget is around £1,500 (live in UK) - can manage another £100 at a stretch - and I was thinking that I could build my own PC instead. It will mostly (99%) be used for gaming - ideally I want to be able to max-out my graphics settings. I also want to try and make my PC "future-proof" - if i'm spending £1500, I want it to stand the test of time. Here are my initial thoughts:
CPU
Thinking about the
Dual Core E6700 (£350). Would like the
X6800 , but not sure that its worth the extra £300 as this would mean half my budget spent on the processor alone. Then again, I could go for the
E6600, and save £150 to spend elsewhere
As Shaun stated, get a e6600 instead, it is the most cost effective CPU.
Graphics Card
Would like something in the
GeForce 8800 range, which would be another £350-400. Not sure on the difference between the different manufacturers (Palit, Asus, Leadtek), or if its worth spending an extra £100 to get a GTX?
I think the GTX is worth it over the GTS, in essence, I believe it is worth spending the extra £100 but the GTS is excellent for its price also. HOWEVER, I recommend waiting some 3 weeks for the current inflated prices for these cards to go down.... or not.
Memory / RAM
Got to be 2Gb of DDR2 - I'm not sure on the difference in performance between a
DDR2 800 Mhz and a
DDR2 1066 Mhz though (other than price!)

I suppose that as RAM is probably the easiest thing to upgrade on a PC, I could always go for the cheaper option and then upgrade 1-2 years later.
You don't even need 800Mhz RAM unless you overclock, so 1066Mhz RAM is absurd, sometimes even for overclockers.
Sound card
No real thoughts on this - would like surround sound as my speakers are compatible. Don't want to spend too much of my budget on this.
Get a Xi-fi or an Audigy 2ZS, depends how much you want to spend.
Hard drive
Space is not really a big issue - only have about 5Gb of MP3s, so could get away with 120Gb. Performance is more important to me - is it worth getting a Raptor? I'm not really sure on the difference that the cache size or the rpm makes to system performance.
No it's not worth getting a Raptor..... their cost does not warrant their gains in performance (which are little in gaming and general applications)
Motherboard
This is one area where I really don't have a clue. Obviously it needs to be compatible with my Processor / GC / RAM, but I have no idea how to find this out. Initially, I won't be OC, but this may be something I want to do later on.
Get a Asus P5B Deluxe. It is currently the king of C2D motherboards.
Power Supply
Again - I don't really have a clue. As mentioned above, initially I won't be OC, but I probably will want to at some point in the future, so fan / cooling system would be important.
Refer to the guide I linked to. I recommend a Seasonic S12/M12 Unit or a OCZ GameXStream Unit.
CD / Dvd Drive
Need a Dvd drive and CD-RW capability - don't need Dvd-RW.
Case
I want something stylish (not too plain!) - and obviously it will have to fit all my components inside. Would like at least 4 USB ports, but I can always get a hub. Thinking about an Aluminium case - something in black or silver like
this.
Would like
this one 
- but think that spending £150 on a case is a bit silly!
Monitor / Mouse / Keyboard / Speakers - already have so don't need including in the budget :thumbsup4
Suggestions / thoughts / comments welcome!
The old spec was:
- Pentium III 1Ghz CPU
- 512Mb RAM
- 40Gb HD
- GeForce FX 5500 256Mb Graphics
