Also I play most games at 1280x1024 since my monitor is a 17" LG Flatron L1710B it's fairly old but works perfectly even with 1080P videos (When i ahd the HD 6870 in) i noticed the bottlenecking because playing games in high detail such as world of warcraft would give me low frame rate even on medium settings.
I'd recommend the 965 heartily. It's a great processor. It only loses slightly to the i3 2100 (By like, 1-3%), and costs £40 less. In multi-threaded applications, the 965 beats the i3 by a fair margin.
Or even if you want to run multiple applications at once. That is when the 965 will tank against any of the i3 processors, due to the 965 having four cores rather than 2.
Ok i found an AMD FX-6100 would this be better for my HD 6870 and will i get any bottleneck from it?
i'll list the spec below
4GB DDR3 1333mhz
500W Branded PSU
Onboard Graphics (Will Be Replaced With HD 6870)
Would you say this is good enough for my HD 6870?
Not sure on the PSU but if i need to upgrade it i will. Many thanks
Looks good to me though I would go for a FX-6300 instead. I liked the Novatech system in your original link above. The only thing I had a problem with is that it did not tell you the make and model of the motherboard.
Also if you ever intend to crossfire another 6870 down the road you'll probably need a better psu and motherboard as the one shown in the Novetech site lists the second PCIE interface as X4 in crossfire mode.
