New Mobo, CPU for <$500

Hello. I'm having computer problems and I'm not sure what's wrong with it. I've tried multiple solutions and none have worked so I'm thinking it's just time for an upgrade.

Basically, I have two questions:

1. Can I use my current DDR2 800mhz RAM if I upgrade to a current-gen CPU/Mobo

2. If not, then what's the best CPU/Mobo/RAM I can get for < $500

Thanks.

you can't use DDR2 on a modern DDR3 mobo.

however, you can get a very solid AMD build for less than $500!

AMD Phenom II X6 1090T: $200
G.Skill 8 GB DDR3-1333: $78
AS Rock 870 Extreme 3: $90
---
$368

If you have a good amount of decent DDR2, then you could just get an AM2+ motherboard and reuse it.

There isn't a huge disparity in performance between DDR2 and DDR3. Link Link Link

However, if your budget is $500 for just a CPU and motherboard (and memory?), then you could easily get a nice X4, DDR3, and a decent motherboard.

What is the full specs of your current system?

I don't know why I assumed you were running an AMD... my bad.

Read the links I posted. There is a very small difference in DDR2 vs DDR3.

It depends on your return-of-investment. If your budget is low and you will be hanging on to the computer for a while, just reuse your DDR2 with a new(er) 775 motherboard.

After reading your linked thread, it doesn't sound like you've narrowed down the problem yet. What PSU are you using?

that 900W is probly overkill. But what brand is it?

For $500, you can also build a AMD system with an athlon II X4, a GTX 460 or HD 6850, 4 GB of DDR3, a 1 TB HDD, and reuse your current case and PSU.

errrrrg. I haven't heard of that brand.

anyone else?

if you can see it, there should be a stamp on the side of listed amperages.

Rocketfish is Best Buys house brands most of their psus are junk, how about amperage and rails?

*EDIT read about this one it's supposed to be decent, I'd like ramps+amperage though as I haven't found specs
