Hey guys i recently purchased a msi gtx 750ti to use it with my core 2 duo e8500. I used to use a gt210 for gaming and got temps of around 50-60. Now i try to play games and some games stutter like bf3 stutters even on medium while my card can play it on ultra and my temps rise to 80-90. Any solutions, i dont wanna spend anymore and will get an upgrade in christmas(i hope). thanks. :)
 
Solution

You need to check the CPU cooler. Those temps are way too high. Even when it was "only" at 80 (I am assuming celcius?) it was too high. You might need some new thermal paste and to clean dust out of the heat sink...

Are those temps your GPU or your CPU? What other settings are you using? Do you have vsync on or off for example. Are you trying to overclock it? Did you use the drivers from the box or did you download them from the Nvidia site?
 
CPU is a bottleneck, yeah. You need at least Core 2 Quad, if you can get a used one cheap somewhere. But definitely list all your components, including the exact PSU model. And yeah, as the cub_fanatic said, are those temps of your GPU of CPU?

Those are the temp of my cpu when on load. I have vsync on for most of the games. i overclocked my pc when i had the gt210 to 4ghz and it had temps of 80 and now i am in stock since even the slightest overclock spikes the temp to 98 degree and above. i have the latest nvidia driver.

I saw a core 2 quad 8300 for 50 dollars but its weaker then my cpu and the only advantage is the cores.My psu is i think an intex 450w something, got it free when i bought a cabinet from a local store. I have a gigabyte g31m-es2l as my primary mobo and 4gigs of ddr2.

You need to check the CPU cooler. Those temps are way too high. Even when it was "only" at 80 (I am assuming celcius?) it was too high. You might need some new thermal paste and to clean dust out of the heat sink and fans. Since it is a Core2 Duo, it probably has very old thermal paste. When thermal paste gets old, it dries up and gets hard like clay. When it hardens, instead of transferring the heat away from the CPU and into the heat sink to be removed, it traps the heat inside the CPU. If you are still using the stock Intel cooler, you should probably get a new one. But, then again, you should get a new CPU. If you do get a new CPU cooler, get something like a Hyper 212+ or EVO since it can be in the Core2 PC and also be reused in an 1155 or 1150 PC as well as a newer AMD PC if you decide to upgrade.
 
Solution
I can only confirm everything that cub_fanatic suggested. And may I add that if you go for Core 2 Quad, go for Q9550 or higher. But be warned, your PSU is quite weak and of poor quality. It would be wise to upgrade it to XFX Core 550 or higher, or Corsair AX/HX/TX/RM, or pretty much any Seasonic.

A good PSU can be reused with your next build. And so can the CPU cooler. At the moment, you have 2 issues: overheating CPU and too weak CPU in general.
 
Your CPU was running cooler before because it was probably just idling to keep up with a 210 GPU. Now that it's having to run at 100% the overheating got worse. Fix the cooling first and see if it gets better. The CPU may be throttling down to keep temps under control and you will probably get better fps once you get the new cooler. Also like Cub said, check the thermal paste and make sure it's mounted correctly because the stock cooler shouldn't let it get that high anyway.

That is a very nice and big looking cooler. It looks a lot like the Hyper 212+ but with one less heat pipe which really won't make a huge difference.

As for the Q9550, what motherboard do you have? The E2220 is an 800 MHz FSB CPU. The E8500 is a 1333 MHz FSB CPU. If you are running the E8500 in a motherboard with an 800 MHz FSB you are losing a lot of clock speed. Basically, you will be running it at around 1.9 GHz instead of its stock 3.16 GHz. Unless your motherboard supports overclocking or is a native 1333 MHz FSB, putting a Q9550 (or even an E8500) is a waste. And if your board is an 800 MHz FSB and you are overclocking it to 1333 MHz, that would explain why your CPU is getting so damn hot. You should at least get a board with a 1333 MHz FSB. If you do have such a board, then disregard this. I was basing my assumption on your original E2220 CPU. And if you can't find a Q9550 (which are really expensive anyway) look for a Q6700 or Q6600 which are selling in the $40-50 range. You can also use the Xeon LGA 771 equivalent if you have a 1333 FSB LGA 775 motherboard because someone figured out an easy hack for it. Here is a beginner's tutorial on how it is done: (link). With a Xeon, you will actually get a better CPU than the equivalent Core2 Quad because Xeons were designed for Workstations and Servers so they can take more heat, more voltage, overclock higher, use less power and they are more durable because they have a higher TDP and were designed to be on 24 hours a day, 7 days a week. Take a Q9550 for example, they are going for over $100 USD on ebay right now. The Xeon E5440 which is basically identical to the Q9550 is selling for $40 because everybody (mostly budget PC gamers like us) wants the LGA 775 version. Same goes for server RAM which is not compatible with desktop boards. Server RAM and CPUs were actually more expensive when they came out but now the desktop parts are more expensive on the second hand market. The good news is that you can at least use a server CPU and save $50 or so. Another great budget chip: the E5450 (1333 FSB) or E5472 (1600 FSB), both of which have the same clock speed, quad core, 12 MB cache specs of the QX9650 which is still selling for $180-200 used on ebay. Both those Xeon chips I mentioned, which are the same in almost every way except one has an even faster FSB speed, are selling for around $50 a pop. That is something to think about for a budget builder like yourself. If you have a board that can overclock the FSB to 1600 MHz, the E5472 is about the fastest CPU you can put on it and your PC will be pretty beastly for what you would have ended up paying for it. It won't be in the same ballpark as a Haswell i5 but it will be playing all the newest games with that 750ti and you it won't be running at 90c.

I have a gigabyte g41m-es2l and a g41m-combo. http://www.gigabyte.com/products/product-page.aspx?pid=... . The g31m has 800, 1066, 1333 and 1600 mhz as fsb as for the g41m-cobo http://www.gigabyte.com/products/product-page.aspx?pid=... it also has the same fsb but my lan is not working so i have the g31m currently and the g41m also cannot overclock. U mentioned the xeon chips, are they good for gaming? For what i know they are not used for gaming and i am getting e5405 at 3000 rupees.
