After only owning my 710 x3 790fx for 4months built my wifes pc died and I decided to hand over my pc to her and buid me a new one. I am keeping my 4870 1Gb and I really wanted to crossfire another one since everyone is buying the 5870. I will be doing strictly gaming on the pc and plan to overclock the hell out of my new processor. But being and AMD fanboy I am really wanted to get me the 955 p2.

I will be buying new ram new cpu and new mobo. Since I already have a 4870 I wanted a mobo that supports cf. But I really want to get the i5 since its only 199. In the long run will it be better to get me a 940 p2 or go for intel instead and buy me the i5. The only downside on the i5 is that no other cpu will be supported for that mobo. Thus limiting my upgrade in the future. then again we upgrade about every 2yrs.

Will I be better off with the i5? Since I plan to get ddr3 as well.

I really want to know wich is better for overclocking and take advantage of my 4870 or better yet a new graphics card here in the next months.

the 750 is not the inly 1156 cpu, there is the 860 and 870, im an amd fanboi also, but remember, the x3 720 at stock keeps up pace with the i7 920 even if its overclocked, no game can use all that processing power, id suggest keeping ur 790fx board and getting the c3 965 which will be $195 and only 125w tdp, also it goes to 4.0ghz by simply raising the multiplier

The difference is really up to which ever company you prefer. Both processors overclock fairly well. If you plan to use your computer for more than gaming I would recommend the i5.

But even when the phenom is overclocked ive seen the i5 and the i7 beating the phenoms at lower speeds wich means that at higher speeds it will beat it even more right?

On Air the 750 overclocks a bit higher IMO.... I have seen several 750's hit 4.5Ghz on Air like it's nothing....955's are known to hit a wall at around 4.1/4.2Ghz. One thing you should know is that you won't see a difference in speed with anything over 4Ghz unless you are running a benchmark. For daily tasks anything over 3.8/3.9Ghz is useless.

PII is not very good in OCing and need water cooling to reach 4.0GHz, whereas the i5 can easily reach 4.2GHz on Air.

In addition, i5@2.66GHz is not much but significantly better than PII-955@3.2GHz and therefore PII-955 will be completely wiped out with both of them OCed to their average max potential(3.8GHz for PII-955 and 4.2GHz for i5) as you thought.

However, PII-955@3.8GHz is more than sufficient in most cases and so it would be a better buy for purely gaming!

ahh ok I think I have made my mind and go with amd. However im getting a new motherboard because my wife doesnt want to let go of that motherboard because of "how pretty it looks." Wich Mobo would you suggest for overclocking the 965

ps I forgot to mention that I am considering 2 pcxpress slots even if they run at 8x. I've read that even at 8x I wont loos that much perfomance is this true?

955 is the best choice for gaming! Get i5 instead if you want a 965.

also I found this sticks and have read good reviews on OCZ i plan to stick with 4gigs for a while. http://www.newegg.com/Product/Product.aspx?Item=N82E168...

Not sure if this would be the best ones for under 100?

This RAM operates at 1.9V which is well above the specification given by Intel(1.65V)! 1.7V might be alright, but 1.9V is just too high.

EDIT: Wait a sec.... This is an AMD instead! You'd better download the m/b manual to check if 1.9V is OK.

Both should be fine. However, I would get the G.Skill one as there's no review on the OCZ RAM. In addition, it's much more expensive than the G.Skill RAM.

*EDIT*
It seems that V8 doesn't support Phenom II, so go for Mugen II. By the way, Mugen II is ranked as the third for the very hot i7-9xx!

However, BE AWARE that this cooler is very high(158mm).
