Time to update the system

okay its getting on that time as my computer was pretty top of the line in its day but now its showing its age. my current build is -

q6700 2.66ghz quad core processor (liquid cooling)
asus p5n-e (nforce 650i sli) mobo
2x Evga 8800gt
4 gb ddr2
800w psu

ive just ordered 2x gtx460 so with that out of the way its time for a new cpu which in turn means i need a new mobo and ram(and possibly power supply but i hope not)
so really my question is what type of cpu should i get? i cant decide whether to go top of the line I5 or mid line I7. price is a factor but when im already going to be shelling out 250-300$ on a cpu another couple dollars wont hurt. once i get this decided then the mobo should fall into place alot easier since most are processor dependant then the ram will fall from there. it wouldnt hurt if you gave suggestion on the board and ram though :) 

edit: just as a side note. the real reason im updating past the GPUs is because i fear that my cpu with start to bottle neck things soon

Sandybridge is only a few months away, and the i5 "2500K" should be a really great overclocking part. Just hold out a bit.

If you must get one now, then a good P55 board with an i7-875K is the way I would go:

I agree: put yor SLI 460s in your current machine and wait just 6 months

You have 2 options you could overclock what you have now (unless you already have)and wait for sandybridge to come, or buy and build a new rig. Sandybridge is suppose to be a 1366 socket now wether or not they produce any 1156 CPU's who knows until it happens.

If you go with a P55 rig I would get an i5 750 or i7 860 the price per performance is great, for a motherboard I would get either the EVGA P55 SLI 132-LF-E655-KR


as for an X58 rig an i7 930 is about the same price as an i7 860, for a motherboard I would get the GIGABYTE GA-X58A-UD3R.

If the 800w PSU is a good name brand PSU than it should be more than enough for what you have if you stepped up later to a pair of 470's I would upgrade the PSU.

Dont forget you will have to upgrade memory and the cooler unless you can get the brackets for your waterblock. But I would recommend upgrading the cooler because the surface of both 1156 and 1366 CPU's is quite abit larger. Not saying you waterblock wouldn't cool it good enough to overclock but I have noticed that the 775 socket coolers dont cool the i5 and i7 as well.

With your liquid cooling you should have good headroom for overclocking. Stick those 460´s in there and let that Q6700 stretch the legs a little bit before retirement.

Liquid cooling does not always mean good cooling :)

i think ive been convinced to oc my current cpu for now. i guess that should have been my question to start with. but now i have a couple new questions. first im more familiar and its easier to oc gpus so could someone point me in the direction of a good cpu oc guide? and then second since im going to wait how much would you guesstimate the i5 2500k and the i7 2600k would cost because if its not much more than a good i7 cpu now then i may invest in the 2600 as i should have a little more money saved up by then

I agree with rolli59, if you are going to retire it retire it right and do some overclocking. Besides, in games the upgrade would provide minimal performance increases. You still have a hell of a rig abuse it.

I think Anand made some guesses at prices in the article... my impression is that they will be quite similar to current prices for this gen.

Here is a very good guide. Don't try shortcuts, read everything, and you should be fine.

thanks for all the help! i just have one more question that i can think of. is Xion a good psu brand? ive never heard really bad things but ive never heard anything good about it either

Not usually good, but they may sell some good units. Like most brands they do not make PSUs but buy them from various OEMs.

See the PSU guide linked in my sig.
