I have a radeon 6670 2gb ddr3 paired with my Athlon X4 760k and I need a new gpu. I'm looking into the r9 270x but there is the 2gb gddr5 and the 4gb gddr5. Will the 4gb model bottleneck my cpu?
Onboard graphics memory is not a factor in CPU bottlenecking; the GPU's performance is. More graphics memory (GDDR5 in this case) allows you to use more displays simultaneously, and higher quality textures without affecting FPS, since the GPU won't have to offload data to slower DDR3. Your Athlon and 270x is a bad pair since the GPU far outperforms the CPU. You'll likely see negligable or no fps gain in BeamNG.
A 6670 is pretty good for it, since their performance is well matched. Upgrading both the CPU and GPU would be more beneficial here. Pick up an A10-6800k (~$140USD) and an R9 270 (~$170USD) if you can afford it. These will work with your old hardware.
I've made a mistake. You don't need to upgrade your CPU since the 760k and 6800k are about the same in terms of performance. 270X is still overkill for the CPU. Not much you can do since 760k and 6800k are about the fastest FM2 CPUs you can get.
Are you sure because a lot of people lie to me a lot - - - Updated - - - So will a 260x or a 750ti or 760ti work? If so, which gpu?
Yes, basically any PCI-E GPU will work fine as long as you have a good enough PSU with the needed connectors. Any of the ones you listed should work perfectly fine.
You'll need a newer CPU and a motherboard with a socket that can take it if you want a build that uses everything those GPUs have to offer. It's pointless to upgrade your GPU with a CPU as weak as the 760k.
Ok but the only cpu I can get my hands on at the moment is the 6800k. Will that make a difference at all in performance?
Time for a new motherboard. Seriously, that AMD CPU is the best they offer in that socket and it is total crap (I have the AM3+ version of it in my desktop). And architectural changes over the years leave it only marginally higher performance than the low voltage core i3 in my laptop. Desktop: 3.4ghz, laptop 1.8. That's embarrassing really that something half the clock speed can almost catch up with it. Get a new motherboard with either AM3+ or whatever Intel want to call their current Intel socket. Get a decent processor. Upgrade the GPU another day, any new GPU will be CPU bottlenecked on that rig.
What about the Pentium G3258? I heard it runs circles around the 760k for gamimg and it is a lot more efficient.
Its single core performance is quite good, 3.2ghz on a haswell architecture. However it is a dual core chip and lacks hyperthreading. If you can live with just 2 cores, it is indeed a good budget option (it also overclocks really nicely to give some incredible single core performance for a £53 cpu) but that may actually be a significant bottleneck. Most games now are using 2 or 3 threads, 2 threads is fine on a dual core, but what about all the OS and background stuff which also want a core? Really quad is best for gaming. BeamNG also uses 1 thread per vehicle, a dual core, not going to get many vehicles out of the game (well, maybe 2). I'd just wait, scrape the cash together and go for a 4690 or 4690K.
If you don't want to get a new motherboard but still have good performance then get the 860k it just came out and is 85$ it performs 25% better than the 760k Correction: 29% better CPU benchmark scores 860k: 5850 ~ 760k: 4550 ~
I can get a new motherboard I just want a good but relatively cheap cpu and a good gpu to run beaming very very well... My Athlon 760k runs almost every car good except the moonhawk. On lowest settings, the moonhawk lags a lot at less than 25fps. But on my I5 ultra book, on low settings, it runs the moonhawk on 35-45 fps. I have max budget of $200 to spend on cpu and mobo and I prefer msi for my motherboard because it is easier to work with for overclocking and other basic things. Intel or and I don't care I need to run beaming at great performance
What I meant was that they will work in your PC but they will probably bottleneck your CPU. You should just upgrade your CPU/motherboard and then do the GPU. Or do it the other way around/all at once. I used to have an A8-3850 and a 650ti then I upgraded to a Radeon R9 270 which bottlenecked the CPU but like 4 months ago I bought a new motherboard and CPU and I've been happy with it since.
