Advice on upgrading / troubleshooting

[bigjonsp]

I've built this system a couple years back and have been trying to figure out why lately it has been hanging up when watching video, either streaming from the web or playing from a file.

I'm thinking of upgrading and was wondering what would be the best bang for my buck?
I have a feeling that my hard drives are contributing to my problems but since I'm not a super tech person I may have mismatched parts when I put this thing together.

I'm looking to spend no more than $500 on my upgrades, but I'm not sure where to put my money.

I play games occasionally but mostly internet and video watching/editing. I will be hooking this up to my 48" tv in the next couple of months, and probably be gaming more on it as well as doing more video watching.

Any advice / ideas are much appreciated.

Thanks

Don't forget a GOOD power supply!

I was really hoping to not have to rebuild my system by keeping the cpu and mobo.

Are there any suggestions (other than getting a bigger power supply, mine is currently a 650w) on where to spend my money?

and is ssd really worth the cost per gb?

I didn't say get a bigger PSU I said get a better PSU! Corsair, Seasonic, Enermax, Antec, PCP&C, XFX are all good brands. stay away from Chieftec, Diablotek, Ultra and others like that.

Yes. And you'll have about enough left over from the upgrade I proposed to buy this one:
