Best GPU for FX-6300 and MSI 760GM-P23?

fenrir31 · Jul 21, 2017

Hello!
I am about to upgrade my PC, because I bought it 3 years ago and the performance isn't that good anymore.

My current build is:
MSI 760GM-P23
GTX 750 Ti
AMD FX-6300 stock
RAM 12GB (8 + 4 1600 Crucial)
PSU Corsair CX600

And here are my questions:
1. What would be the best GPU for my motherboard and CPU? I guess GTX 770 is a little bit too high? I am aiming at GTX 680, will they go well together?

2. Also, I already bought aftermarket CPU cooling and I want to overclock my FX-6300 to at least 4.0Ghz. Is it possible on my motherboard? I really don't feel like changing my MOBO or my CPU. I got Hyper TX3 cooling and I am going to install it tomorrow. I am aware that my MOBO isn't good for overclocking, but I guess I will have to do it NOT to bottleneck my new GPU. Is 4.0Ghz possible? Also how should I do it safely? 4.0Ghz + 1.3 voltage (so 0 changes on voltage, actually) + aftermarket CPU cooling can work out well on my MOBO? And if the answer is yes, is GTX 680 the best choice here? And I would rather stick with nVidia, I don't really like AMD GPUs.

Thanks, guys!

1) I guess you don't want to buy new, huh? (Those are old-ish cards) The GTX 680 and GTX 770 are about equal in performance. The 680 requiring a slightly less wattage PSU. (680/550W- 770/575W) OC'ing the CPU will also increase the wattage demand on the PSU.
Note: One of the GTX 1050 Ti OC models would be roughly as powerful at ~$160 if you're interested.

2) You're right, that board is not designed for OC'ing. However, that doesn't stop most folks from doing it anyway. Just be aware you do so at your own risk. If you are only trying for 4GHz, any board should handle that w/o much issue. And you can probably get that w/o having to raise the vcore (voltage). The turbo mode is 4.1GHz. Simply disable CIE and turbo mode, and start increasing the CPU multiplier. On that board I believe the multi is called "adjust CPu Ratio". This is done in BIOS in the Cell menu portion.

Yes, I would rather get an used one, they are a lot cheaper. I was thinking about 1050 Ti 4GB, but they are kinda expensive in Poland since they are pretty new and people don't sell used ones often. Used 680 or 770 is 2x cheaper than 1050 Ti. But I will surely consider that anyway.

And aboout my CPU - Yeah, I think I know how to doit, I did overclock it before, but I was 15 or maybe 16 years old and I had no idea about voltages or so and I was overheating and getting FPS drops so I just resetted it back to stock and never did it again. But yeah, that was 3 years ago. Guess I am gonna turn off all turbo options, clean my pc out of all dust, install new cooling and thermal paste and pray for overclocking gods not to overheat with 4.0ghz and stock 1.3 voltage. Thanks a lot, you helped me!

And wattage of gpu or cpu doesn't matter, my PSU is 600W corsair so it's enough for everything

Remember, increasing the voltage will not increase the clock speed of the CPU. Clock speed is based on the base clock (bclk) x CPU clock multiplier. Increasing the voltage (vcore) is only done to stabilize the process if/when needed. Leave the vcore alone for now and see how high you get on the multi alone. Then when you finally get an unstable result, you can try tweaking the vcore up a bit in small increments to get the OC stable again. It's the voltage that takes its toll on the system. Especially on boards that aren't designed for it.

Didn't know you were in Poland. Yeah, I imagine newer gfx cards arrive there later than here in the US, and probably at increased prices. Either of those older cards you mentioned will be fine. Still good gaming GPUs, just surpassed by lower wattage faster new stuff. Your PSU should be OK up until when you decide to OC. Then you may be marginal.

So I installed new cooling yesterday and tried a bit of overclocking and OCCT 20min full load test. At 4.0ghz I got a bluescreen after 90 seconds, at 3.9ghz the test stopped for safety reasons (core #1 problem) at 3.8ghz it was ok for 20 mins. But my cores were dropping to 1.4ghz because of... I don't know the reason, maybe it was temperature, maybe it was fault of my bad MOBO. The test was 100% load for 20 mins, I can't really tell the reason, but I guess OC is pointless at this point. BUT! I guess I will just turn on the Turbo Core in BIOS. Because why not? Since I shouldn't really OC on my MOBO, turbo core will do that for me without the risk of bluescreening or doing something wrong in the process. It will go up to 3.8ghz which is my safety line and decrease it when needed. Isn't turbo core better than static 3.5ghz? Correct me if I am wrong.

Also, for my GPU I am looking for GTX 680 4GB, but if I can't find any good deal I will just go for Asus GTX 770 2GB OC.

The fail to get a stable OC is probably due to the components used on that board. Not stable enough to go beyond stock specs. Turbo mode will be enabled when there are fewer than all 6 cores (3 modules) being used. I believe it is 3.8 GHz if only 4 cores are used and 4.1GHz if only 2 cores are used. But yes, stay with turbo mode enabled.

Depending on the games you like to play and the new games coming out, it may be wiser to go with the extra VRAM of the GTX 680.

I ordered 770 OC already. 680 was a lot more expensive and without any warranty, so 770 with 2 months warranty was a smarter and cheaper choice, hope I am not gonna regret. And yes, I guess it will work good with turbo core and rest of my components. Thanks a lot!
