I'd be willing to wager that the CPU is the bottleneck with the RAM contributing. You should be able to upgrade both without needing a mobo. I'd suggest an i5 level for the 4 cores, of course you need to "k" model to OC.
That's a shame. They're quite expensive.
Yeah, but as you are seeing, the performance is greatly increased. What really sucks is that when your RAM packs up, it increases the load on the CPU and also uses the page file more, which is much slower. Personally, I'd start with the RAM upgrade and see where that gets you.
You could go for a i3 to save some money, but I'm not sure the increase in performance would be enough to justify the cost. However, another avenue you could try is getting a used CPU from a site like eBay. The price is usually much lower than new and I personally have had good luck on there. I've bought about 8 used CPU's from there now and no issue since. CPU's are not like GPU's, which used GPU's are often run hard by ecurrency miners.
For RAM upgrades, I suggest going to Crucial memories website and run their system scanning tool to find out exactly what is compatible, then shop around. However, if you buy from Crucial, they guarantee the RAM is compatible with your motherboard (but guaranteed to be with with your current RAM, that is hit and miss it you can combine RAM modules).
