First off thanks for taking a look at my post.
I am looking to upgrade atleast CPU ( if no other advice for upgrades from readers ) so that when i hand this PC down to my GF's little boy, we can play current games together and he is not struggling terribly with frame rates with games like Bfbc2, bf3, guild wars 2.
the second part of my post will be a Pc im looking to build or order from cyber power and any advice on parts for that build is welcome.
Specs for the Current PC i have.
Mobo: MSI p6n Sli nforce 650i
Ram: 6gb Corsair XMS3 or 2..uhh.
PSU: corsair TX850W
Video: Nvidia gtx260
Monitor: Samsung PX2370 23inch LED
CPU: e6750 2.66 with slight OC to 2.8ghz on stock air cooler (2.9 and 3.0ghz causes computer to freeze while playing games = (. )
I was thinking of upgrading to one of these 3 cpu's - Q6600, Q6700 or qx6850 if i could find any for decent price on ebay
and then if needed possibly a 560ti for gpu ( only if needed )
1a. Would i see any sort of increase in FPS with games mentioned above with any of those procs and which one is most worth my money.
2a. do i need to upgrade the GPU as well and if so would the 560ti be bottlenecked by any of the above mentioned procs
RAM should be DDR2, for mobo.
Whilst upgrading CPU may give benefits in other areas, I don't see it giving any real benefit in terms of gaming frame rates. You will still be limited by gfx. Changing that, to GTX 560Ti, as well, should, in theory, give you reasonable performance in, say, BF3, with current monitor. I'm not sure, though, whether you might then find mobo/RAM is limiting things a bit.
If there are no actual issues, with current CPU, one possible option would be to upgrade gfx, first, and then "see where you are".
To be honest, if you are planning a new build, in a few months, I'm not really convinced of the benefits of a "slightly dubious" upgrade now, but that's, obviously, your personal choice.
Regarding new build, apart from a few tweaks, fine. If you are going to get a high res 27" monitor, it may be worth considering a few different options.
