I recently purchased a new graphics card, a EVGA 1070 sc and apparently from many reviews and a lot of forum reading, this is suppose to be a really really decent graphics card that can run recent games i.e Overwatch, BF1, etc on Ultra/High. The problem is, which I just found out recently, is that my CPU is actually terrible for this card, meaning my previous graphics card ran most of my games on Low, and now even my new 1070 run the games on low! I really need some new recommendations, that can go well with my graphics card. I don't mind buying another CPU with a graphics card already in it, I wouldn't mind taking it out and upgrading it with my 1070. Here are my current specs if you're interested. Thank you for taking your time to read this :)
(Note: my monitor is also new, NVIDIA 3D Vision)


MOTHERBOARD: LENOVO Bantry CRB (P0)
Edition: Windows 10 Home
System Manufacturer: Lenovo
Version: 1607
OS Build: 14393.447
Processor: AMD A8-7600 Radeon R7, Compute Cores 4C +6 3.10 GHz
Installed RAM: 16.0 GB
System type: 64-bit operating system, x64-based processor

Yep. Going with A or B will "unlock" the GTX 1070 full potential.

If...

Standard warning: some pre-built PCs have a locked BIOS which restricts component changes.

For situations like this, it's the motherboard information which is most useful because it's the one component which determines which processors can be installed on it. Download something like Speccy and that will give you your motherboard information which can be used to determine what can be used with it; this is assuming the BIOS isn't locked. (Personally haven't heard about the problem with Lenovo, usually it's Dell or HP...)

Bad news: even without the motherboard information, the FM2+ socket's most powerful processors are the A10-7890k and the X4 880k. Both won't get the most out of the GTX 1070; presently you'd really need an Intel CPU system to get the most out of it.

Hey it's me again guys, coming back to you with the mother board
System manufacturer: Lenovo
System Mode: 90AY000AUS

googled those two and i got this, the original computer i purchased. I'm not entirely sure if it's helpful in determining what the motherboard is, but this is the only way i know how

*Edit: Motherboard for this PC is LENOVO Bantry CRB (P0)
downloaded speccy like someone suggested (thank you)

Based on the following thread on a similar topic an A10-7800 APU should be compatible.


http://www.tomshardware.com/answers/id-3192060/amd-processors-run-lenovo-bantry-crb-motherboard.html


However, you should be aware that while the A10-7800 will likely give you a little better performance, it will still bottleneck the GTX 1070. AMD FX series CPU are not really all that good for games that are CPU bound. AMD's A series APU has even less processing performance.

Below is a CPU benchmark for Battlefield 1 pairing up several AMD and Intel CPUs with the GTX 1080. There are no APUs in this CPU benchmark, but generally speaking the FX series CPUs gives better performance.

http://www.techspot.com/review/1267-battlefield-1-benchmarks/page4.html


Generally speaking, AMD CPUs (and APUs) do not fair well against Intel CPU when it comes to games a dual core i3-6100 CPU provided slightly better performance than the quad core FX-8370 using DX11 and pretty similar performance when using DX12. Apparently BF1 has performance issues with DX12 because minimum FPS in DX12 is a lot lower than the minimum FPS in DX11.

The performance of the A10-7800 APU would be a bit less than the FX-4320 which is at the bottom of the performance chart. Granted these results are for the more powerful GTX 1080, but the gap in performance would be similar with the GTX 1070. The best advice I can give you is to save up money to either buy new PC with a Core i5 CPU, or to build you own PC around a Core i5. Alternatively, AMD will be releasing the Zen CPU which is the successor to FX-8xxx / 9xxx series. But it will be using the new AM4 socket and no one is sure how comparable the Zen will be compared to Intel CPUs.

AMD's Zen CPU does not have to beat Intel CPUs (though that would be a nice surprise). The Zen only needs to show that it is a significant improvement to the current FX CPUs to be competitive with Intel.

I recall another forum member having the same motherboard, and I didn't find much information at the time. Not much more information now either. I assume it's because it is propriety hardware, more so given the name... But if the GTX 1070 works on your PC, then BIOS is likely not locked. But some motherboards may need a BIOS update for certain processors to function correctly.

What we know is the A8-7600 is an FM2+ processor with a TDP of 65W.

Assuming the motherboard only allows up to that TDP limit (which seems unlikely), then an A10-7860K and X4 845 should be possible as both have a TDP of 65W too. The A10-7890k and X4 880k have a TDP of 95W. All subject to the BIOS. In either case, I would favour the CPU over the APU (CPU + GPU) as you wouldn't be spending money on something you won't be using (the integrated graphics), i.e. the X4 845 or the X4 880k.

With my previous post, I don't believe it to be entirely worthwhile pursuing a CPU upgrade. I don't think you'd be amazed by the slight performance advantage to really appreciate the GTX 1070. As Herc08 suggests, you may want to consider saving your money for a new system.

Overwatch is not a very GPU demanding game. But the benchmarks below shows that there can be pretty significant performance gap between AMD and Intel processors; again using the more powerful GTX 1080. If you only play on a monitor with a 60Hz refresh rate, then I would say whatever CPU or APU (the A10-7870k) does not really matter because the monitor is limited to only displaying a maximum of 60 FPS. However, if you play on a 120Hz or 144Hz monitor, then you can notice the difference in performance between AMD's APUs and FX series CPUs with Intel CPUs dominating the performance chart. But on a 120Hz or 144Hz you would not notice much of a difference when actually playing the game with an AMD CPU or Intel CPU using the GTX 1080 because the FPS is basically close to or exceeds 144 FPS.

Hi, so to gather my options in one thread I have
A) Buy a new PC with a Core i5 CPU and insert my EVGA 1070 gtx SC within that new CPU
B) Save up and build my own PC, and keep the graphics card
C) Upgrade my current CPU with the A10 7800

I really prefer option A, because I'm not really tech savy when it comes to starting from scratch and putting a whole new computer together. But after all this should i expect my graphics card to run at it's actual potential (If i go with option A)? Not like what it is currently?

Many will err towards building your own. As mentioned a few times, upgrading your current APU to the most powerful APU or CPU on the FM2+ socket isn't really worthwhile, certainly not for your intentions.

If you really must buy a new PC, I would suggest avoiding the major builders like Dell and HP who have their products in stores (fearing a locked BIOS, because it would defeat the purpose), and search out smaller companies who use components you can easily identify (chances are you won't be restricted by BIOS as the motherboard will be a consumer market item).

Yep. Going with A or B will "unlock" the GTX 1070 full potential.

If you are not tech savvy then definitely go with option A. Just save up money if you don't have the funds to do so. If you like to stick with AMD, then wait until reviews are out for their Zen CPU to determine if it is a viable alternative to Intel CPU at a lower price. However, I have not kept up to date as to when it is expected to be released.

Option B can save you a little bit of money, or it could cost even more than option A depending on how are you want to customize your own PC. For example, the aluminum PC case I purchased for my home theater PC back in 2009 alone costs $280 (with shipping and tax) with nothing... not even a power supply. However, there are potential pitfalls like one time I received a defective new motherboard which only partially worked but I had to do a lot of testing to determine that since at first it appeared the actual defective part was the new graphics card I purchased.
