I own an a10-5700 apu, a 750 ti from gigabyte. Ive seen benchmarks from people that can push bf4 with this card above 60fps on 64 player paracel strom on medium, yet even on low i cant even get past 55. I only have an fm2 slot mobo so the best i can upgrade to would be a 6800k. would that help or is something else wrong?

Your CPU is probably bottlenecking some. There is a 750k/760k option as well, that would allow you to overclock, unless you are on an OEM system.

A "K" series cpu overclocked will certainly help reduce the bottleneck, but you will never run the 750ti at its full capabilities.

i would say yes its holding the 750 back

we dont know what Ghz is OP's APU running at though, but those are surprising results! The haswell i3 should have what, like some 10% gains over the ivy bridge too

You could try overclocking the APU and see if you get better performance

Well a 750ti on ultra (on 1080p I'm assuming you have?) would never get 60fps constant, more so around 40ish and you could tweak some stuff to get the FPS higher like turning off MSAA. I have an i5 3570k 4.2ghz and the much stronger hd7950 and even I don't get 60fps constant on this game, it's just buggy. There was a guy the other day with the 8 core 8350 and r9 290 and he got fps dips too


My bro has an a10 5800k (4.2ghz it turbo boosts to) and a gtx660ti 2gb Superclocked and me and him generally get the same FPS, on Shangai 64man conquest on 1080p ultra, his dipped to 35fps at the worst and mine was about 40 at the worst. Those APU quad cores when clocked high enough are pretty decent when paired with a good GPU.


The 750ti is good on a budget but I think you overestimated what it could do paired with your lower clocked (and locked) CPU. It was NEVER going to max out stuff on ultra at 60fps with that combo.

Those cheap motherboards generally paired with the locked APUs are generally crap too, I'd suggest on a budget the Athlon x4 750k and an A88X motherboard and a CM Hyper 212 EVO cooler and overclock it, or just tweak the settings around till you get better fps, your CPU is holding you back, because 1:Intel is much stronger per core anyway, and 2:Your APU is clocked much lower than an unlocked one could go

I'm assuming it's a prebuilt, so you'd need a better power supply too when overclocking the Athlon x4 750k, it's a 100tdp cpu and I wouldn't risk overclocking anything at all on those sucky POS OEM PSU's

Shouldnt be bottlenecking it mite be a bad card. Iv seen the 7850k oc 4.6 ghz with a gtx 780. Getting 120-60fps on ultra preset.

well yea but he has a much lower clocked and locked apu and a much worse gpu than a gtx 780. When clocked high and paired with a good gpu these quadcore apus can play stuff on ultra pretty good. It would need to be at least at about 4.2ghz though. If the OP is even still around they could just plop in an Athlon x4 760k and that should be clocked high enough to help, as well as tuning settings, because the 750ti is good for the money but not the strongest card in the world by far. The other budget gpu r7 265 (hd 7850 rebrand) is better but consumes more power.

depending on how low wattage of a PSU the OP has, and I'm going by the assumption it's a crap prebuilt pc PSU, they would need to upgrade. Probably one of the reasons a low clocked less power hungry APU was included in the pc to begin with
