Least expensive CPU/GPU to run SSBM/SSBPM netplay while recording?

[yl-smash]

The G3220 would suffice. Smash games are light weight. That being said, you should be patient and save up for a more future-proof cpu rather than rush to get whatever works. The upcoming Pentium Anniversary cpu's could be worth waiting for too, they're going to be unlocked and will be released soon.
