Will my CPU bottleneck with my GPU?

jwk2608 · Apr 2, 2014

Im trying to add a GPU to my computer right now and had some questions.

1. Are those GPU too high end for my CPU?
2. Which GPU do you recommend? I will use my computer for mostly gaming.
3. Any Tips when installing my GPU? I am concerned cause my CPU has integrated graphics. I think I heard somewhere that I need to delete this before installing my GPU... not sure

My specs:
-Processor: A10-6700 3.7ghz
-10gb Ram DDR3
-1Tb HDD

GPU:
-MSI R9 270 GAMING 2GB 256-Bit GDDR5 HDCP Ready CrossFireX Support Video Card
-GTX 750 Ti

I doubt a bottleneck would be present - the A10 performs slightly above what you'd get out of a Phenom II x4 at the same clock speed, if my numbers are correct, and that's more than enough to drive an R9-270. I wouldn't recommend anything larger than the two cards listed, though, as you would run into a bit of a bottleneck.

I'd go with the MSI R9-270 you listed - I like MSI as a company in the first place, and the 270 is an excellent card with more than enough power for today's games. I actually used an HD 5770, and even now it's only bee replaced with a mobile GTX 660M; I can run just about everything at max settings at 1080p, and both of these cards don't even compare to a desktop R9. I think you'll be very happy.

You'll probably have to disable the iGPU in your motherboard BIOS, but I can't say for sure as I've never actually owned an APU. Definitely uninstall the video drivers currently on your system and back everything up just in case - I'll let someone else fill you in on the more specific details, as I severely lack experience in this area.

Just my opinions. Take 'em for what they're worth.

the a10 6700 is not a bad little quad core if you paired it with a r9 270 you would probably get pretty good performance

Either of those gfx cards will be fine with the A10-6700. So...
1) No
2) If you have enough PSU, the R9-270 would be a bit faster than the GTX 750 Ti. But most of the 750 Ti's don't need a 6 pin aux power connector if that matters for you.
3) If you installed the gfx driver from AMD for your APU, uninstall it in control panel. Then shut down and install the new card. Boot and install the latest driver for your card and OS.

Thank you so much for your help. It really helped me decide on what to get

And actually, I didn't buy my computer yet. This new computer was on sale on Newegg and wanted to just buy it and add a GPU.

may iask why you would buy a computer with an apu just to add a graphics card not to mention that computer has a 300 watt power supply

theonerm2 · Apr 2, 2014

Your power supply might not be up to powering a new graphics card. Regardless I recommend the 750 ti.

im planning on chaning my power supply as well. But I am on a budget and couldn't afford to get a CD-ROM, OS, and the case.
I found this computer and it had everything I needed. Just needed to add a GPU. I don't like how my CPU is an APU but I couldn't find anything better than this for the price.

theonerm2 :

Can you explain how 750 Ti is better? I am new to this field and not sure what to look in a GPU.

coolcole01 · Apr 2, 2014

750 ti would not need a new power supply it runs off the pci e slot

coolcole01 · Apr 2, 2014

but with the card you are going to be spending over 600 which when spent right can get you a very good machine

clutchc · Apr 2, 2014

The GTX 750 Ti is the fastest card you can buy right now that doesn't need a PCIe power cable. But if you upgrade your PSU, the R9-270 would be faster.

but trust me i understand the i want it now feeling

coolcole01 :

darn it you got me. I think I will have to reconsider this. So my friend says AMD GPU are slower than NVIDIA ones... is that true?

clutchc · Apr 2, 2014

jwk2608 :

You're going to start a war...

coolcole01 · Apr 2, 2014

No not true essintially it comes down to money vs performance each side has an answer for the other but the most powerful card right now is an nvidia. But that can change quickly. Speed means almost nothing.

clutchc · Apr 2, 2014

...and it depends heavily on which game.

Will my CPU bottleneck with my GPU?
