I've recently upgraded the graphics card on my pc after years (i bought the pc about 4-5 years ago, prebuilt because i didn't know any better)
And right now i'm looking at upgrading my processor too so that it doesn't bottleneck the graphics card.

 

Intel Celeron G530 (2.4GHz) - Current CPU

AMD Radeon R7 250 (sapphire) - Current GPU

Nvidia GeForce GT 520 (previous GPU)
ATX-500W-E1-PSU - Power Supply 

ASUS p8h61-m lx3 - Motherboard

 

I'm looking for the cheapest CPU that wouldn't bottleneck the GPU, i play at 1366x768 resolution, and i don't really care about playing the newest games at the highest settings, (i'd probably play Battlefield 3 (which i have already played on GT 520 graphics card, at about 30fps on very low with mods for reducing the quality lower than the game allows))

So you're just looking to replace the CPU? Not the motherboard?

 

If so, you should try looking for an LGA 1155 i5 CPU. Like the 2400, 2500(K), 3570(K), etc.

 

Otherwise an i7 could work too, if found at a nice price. i3 could be an option too, but it won't be as good in some newer titles.

 

It just kinda depends on what you can find and what you're looking to spend.

Well, you wouldn't go wrong with an i5 or i3 kaby lake, or littbit more bang for your buck with Ryzen 5 or 3. But that would mean you would need to upgrade mobo and ram. 
If youre not looking to do that, look at your motherboards manufacturing and see which one it supports. But probably its worth the upgrade.

Get the cheapest LGA 1155 CPU,

i5 2400 probably the best cheapest one you can get.

The best to do would be to try to find a i7 2600(k) used

CPU: Intel i7 6700K 4.5 ghz / CPU Cooler: Corsair H100i V2 / Board: Asus Z170-A / GPU: Asus Rog Strix GTX 1070 8GB / RAM: Corsair Vengeance LPX 16GB DDR4 3000 mhz / SSD: Samsung 850 Evo 500 GB / PSU: Corsair RMx 850w / Case: Fractal Design Define S / Keyboard: Corsair MX Silent / Mouse: Logitech G403 / Monitor: Dell 27" TN 1ms 1440p/144hz Gsync

You can find 2600 for like 100$ on ebay

That would be sweet deal and big upgrade for you

CPU: Intel i7 6700K 4.5 ghz / CPU Cooler: Corsair H100i V2 / Board: Asus Z170-A / GPU: Asus Rog Strix GTX 1070 8GB / RAM: Corsair Vengeance LPX 16GB DDR4 3000 mhz / SSD: Samsung 850 Evo 500 GB / PSU: Corsair RMx 850w / Case: Fractal Design Define S / Keyboard: Corsair MX Silent / Mouse: Logitech G403 / Monitor: Dell 27" TN 1ms 1440p/144hz Gsync

Since that your motherboard supports sandy bridge processors which were released in the era that you had bought it, I'd suggest that you look around on the used market for a used i5-2400 or i7-2600, these CPUs can generally be found cheap. So really, any sandy bridge processor will work with your motherboard.

I see most of you are recommending i5 and i7 cpus which are kinda expensive here (Serbia) 
I'm on extreme budget and i think that i3 would be a good choice, because i don't really need to do some extreme stuff, and my budget is about 100$ max
(i also need to upgrade hard drive, if i didn't have to do that i'd have 150 to spend

If your not doing anything extreme in terms of your workloads, i3s are fine for your use case and shouldnt create any bottleneck. They generally go for very cheap on the used market and can be a very good upgrade over your current CPU. When it comes to the HDD, I'd suggest for the maximun storage capacity you should go for a 500GB HDD, they are generally cheap, 1TB is more expensive but is worth the money considering how much storage you get for storing lots of games/programes, but not to say tht 500GB of storage is still a good amount.

i guess so, they go for up to 70% cheaper than i5's here.

 

About the HDD i found a 500gb one for 62.27 USD, but i also found a 1TB version for 72.16 USD which i think is good value for 500GB more (new)

I'd recommend getting the 1TB HDD so you dont run out of storage in the future and its definitely worth the extra $10, if price is something you're worried about, then the 500GB HDD is a decent alternative and adding another 500GB HDD or adding a higher storage capacity HDD is a viable upgrade.

Well the reason I'm probably getting the 1TB one is because the HDD which I currently have (500GB) is dying, and I need an alternative which will hold a lot of stuff (which up until now I had to delete stuff to put more stuff, like movies and games and music) and something that will last me years (which is why I'm buying a new one, instead of a used one which I can get for cheaper, but will probs break in a year if not less)
