is Kuma worth upgrading to?

if you're on a budget, i guess. it'll give you more than 20% of performance boost from your current in terms of clock for clock. and you can oc the kuma more.

but i highly suggest you add $50 and go for an ph2 710 tricore at least. it will give you a lot of performance increase, and a smoother experience since the extra core will be the one handling the background apps.

I would agree with the two above me,
if you are satisfied with your system for the time being - or you can manage using it for another month or two (although not as much fun), I would say see where the prices are in that time.

I use the Kuma, and I like it for the price/value, but since you already have a 2400 @ 2.9ghz, I'm not sure if dumping another $65 into a Kuma for marginal performance increase would be worth it. If I were in your shoes, and price was a factor, I'd probably hang on to what I currently have for a bit longer and, as gerikoh said, pick up a ph2 for better increase in performance for your effort/money.

yeah, go PHII if you are going to upgrade.

Or maybe look for a 9850 or a 9950 used for a good price.

It's probably not worth it. I'd wait a little bit and buy a phenom II 720 if I were you.

depends what you do mate. if you just want a lil boost of performance. yeah get the kuma. if you into gaming and such. 50-60 bucks more a huge amount of performance will increase.

I'd say get a 710. If your board can handle the clock speeds, it'll overclock very well. It's basically the same thing as a 720 with a locked multiplier. Not to mention if/when you want to upgrade to a purely AM3 platform you wont have to buy a new CPU.
