£600 Gamer's build required.

[bartsome]

Hi guys. This is my first post and I need a gaming PC that will be able to play games such as BF3 on High/Ultra and get at least 30FPS.
I only have £600 for now although I'm going to have £200 more by October.
Therefore this is only a backup build.

Approximate Purchase Date: End July latest
Budget Range: £600 inc shipping, vat
System Usage from Most to Least Important: Gaming, YouTube, FaceBook, movies
Are you buying a monitor: Yes, 22" would be nice.
Parts to Upgrade: everything is being bought
Do you need to buy OS: No
Preferred Website(s) for Parts: Anything that sells stuff to UK
Location: London, UK
Parts Preferences: Intel CPU, ATI GPU. I don't want any rubbish too-good-to-be-true deals. Trusted/known brands only.
Overclocking: Yes, light (4.2Ghz approx.)
SLI or Crossfire: Maybe in a year or so
Your Monitor Resolution: Need to buy one (this is included in price), 1920x1080 would be nice
Additional Comments: Must be quiet. Must be upgradable, not gamers only since I'm starting GCSE work. Also, please don't get prices in USD and convert. That never works, prices in the UK are always more than the US. A cheap gaming keyboard/mouse would be nice but not needed.

If I missed out anything, please tell me.
Thanks in advance

That psu isn't enough if he wants to crossfire. However, most people that say they will get around to sli or crossfire dont. Also there is no aftermarket cooler if he wants to overclock.

Also there is no aftermarket cooler if he wants to overclock.

Would the CM Hyper Evo be good enough to get a stable 4.5Ghz overclock?

 

[ScrewySqrl]

yes

 

[bartsome]

yes

Thanks but is there another, better, graphics card I could use? I'd like the 7850 but that's over-budget. I also don't need the 3750K so I can save a tenner on that by getting the 2500K.

 

[ScrewySqrl]

there are some largish gaps in GPUs these days. the 6870 pretty much matches up to the 560/560 ti, then the next step up is the 7850 (the 6950 would be a step under the 7850, but are not cheaper these days)

The fact of the matter is people vastly over estimate CPU needs when @ 1920 x 1080 gaming, the bottleneck shifts firmly to the GPU and to this day many games still do not leverage past >2 cores. In your shoes i advise getting the best GPU your budget allows u and work from there - your gaming performance for the $$ would be greatly improved ^^
