I want to get an i5 2500k sandy bridge
http://www.newegg.com/Product/Product.aspx?Item=N82E168...
but I don't know what to upgrade to
I just upgraded my ati 5770 to a nvidia gtx560ti direct CU II
and a corsair 750w psu
but my q8300 cpu is bottlenecking a few of my games
I cant overclock my cpu since it was factory prebuilt
I dont know about motherboard and all that stuff
what should I do?
my pc model is cg5270
Most likely I wont upgrade my cpu
but I just want to know what should I do if i was going to upgrade
the lag in ARMA 2 is a pain in the butt
only 60 percent gpu usage lol

If you want to upgrade you cpu, you'll have to buy a new mother board if you want a sandybridge... Get a Q9550 and OC it to 3.59GHz with stock voltage... Al lyou do is raise BCLK but get 1600MHz RAM...

That machine has a G43 chipset so an LGA775 socket, but all C2Q still sold today are overpriced (see here).

If you want to upgrade to SandyBridge (the 2500K), you will have to change the motherboard and the RAM, the PSU and video card will work (any old PATA devices might not fit anymore).

1) I would not invest any more in a 775 based system. It is a couple of generations old.

2) After a good graphics card, which you already have, you need a cpu with at least two cores and a high and efficient clock speed.
The 2500K quad is about as good as it gets. Even a duo 2100 will be better than your Q8300. Few games use more than two cores.

3) You will need a 1155 based motherboard. Expect to pay $120-150 for one.

4) You will also need DDR3 ram, expect to pay $40 for 4gb.

5) If you did not recieve a windows disk with your pc that you can reuse, you will also need a copy of windows-7. About $100.

5) DDR2 is more expensive than DDR3, so you might be able to market it on ebay. The Q8300 also.

Unfortunately, I can't do half of what you said, so I have to just stay with my q8300.
In some games it's more than playable
but in some other games
it's either playable but bad performance
or just bad performance

Maybe it's in some "Advanced" menu/submenu hidden by default. For example, the CAS timings on my Gigabyte P35-DS3L (yup, me too I have to upgrade :p ) is hidden by default and I have to press CTRL+F1 for them to show-up.

So I press CTRL and F1?

For my Gigabyte MB yes, might be the same for Asus, I wouldn't know.

Can anyone explain to me the steps of overclocking via bios?



Dont see anywhere to OC.
my cpu temperature lays under 40c in all cores
its just when i startup its high

chill out bro. you bumbed within three hours people dont sit around waiting for you to reply. but to answer your question is that most prebuilt system the overclocking ability is locked out. your options are to get a new mobo to overclock but do yourself a favor and don't fix cancer with a band aide. if you cant afford a new mobo ram and cpu now then save for it. dont buy a 775 based system it is old and out dated and will only get worse. save up for a 1155.

how about software overclocking?
June 28, 2011 7:23:37 AM

Could be in the chipset menu. q8300 requires fsb adjustment to overclock. Your temp (58) is quite high in the pics though.

No my cpu is under 40c at all 4 cores. and nothing usable is at the chipset menus
And im not sure about cpu usage but my gpu usage was low on some games, only 50 percent
where do i find a cheap upgrade like that though?

so that you can overclock. or you buy a new platform type and upgrade the cpu

and a cheap phenom II quadcore. The AMD price to performance just can't be beat. And that motherboard is pretty future proof with USB 3.0 and Sata III.



make sure the board is an am3+ board so that when the new cpu's from amd come out you have the option to upgrade to them

Ok I will upgrade by the end of the year. So now using turbov i can OC my cpu from 333mhz to 342mhz with a 7.5 multiplier. Which is around 65mhz, will I be able to see at least a 2 fps increase in cpu intensive games like ARMA 2 where I really struggle in? My cpu is now like always at 20 percent load but temps are okay
Also, if I OC my gpu, will the bottleneck be less of a issue and will the performance be better?

Looks like 349mhz is stable too, so around a 120mhz gain.

120 mhz is a very mild overclock try for more to like the 3.0 ghz range.

just in comparision, my laptop's cpu is never the bottleneck and its a 2.0 ghz base clock. and it will play most games on high settings. that is the advantage of a Sandy Bridge cpu, they are just way more efficient.

Lol it struggles at 349mhz. even though it's stable, it freezes my pc half of the time I set it from 333 to 349. So I think it's better to leave it at stock.
