E8400 or X3 720

My current computer has an E8400 CPU, EP31-DS3L motherboard, 2GB crucial ballistix (800mhz), HD 4850, and Hiper 530W PSU.
I don't whether to upgrade (replacing HD 4850 with HD 4850 X2, replacing hiper PSU with crosair TX650W and then later a good cooler to oc my CPU, and +2GB crucial ballistix) or buy a new computer (same specs but with x3 720 and ddr3 memory)?
I know that upgrading will save me A LOT of money, but I don't know if the 100% new PC will be more powerful.. I want to save as much money as possible, but I also want my computer to be in date for a good couple of years. What should I do?

More about : e8400 720

i think a new mobo with a new gp andpsu should be fine for now and later u can upgrade to a quad core pc

The problem with that is buying a new motherboard I'd need a new OS..

No need to upgrade.

E8400 and X3 720 are neck and neck in benchmarks.

Plus, When overclocked, the E8400 will probably mop the floor with the 720.

Replacing the E8400 with the X3 720 wouldn't be an upgrade. At most, it would be a "sidegrade" as you will end up with the same perfomance levels.

I would stick with E8400 just for OC possibilities. Plus, it's still one hell of a solid CPU.

Here's the conclusion from Neoseeker's X3 720 review (found here: http://www.neoseeker.com/Articles/Hardware/Reviews/phen...)

"Conclusion

The Phenom II X3 720 Black Edition is an interesting beast.

AMD is doing the right thing in targeting the Core 2 Duo with it - and marketing the 720 based on the price/performance - however they were reaching a bit in targeting the E8400. The Phenom II X3 720 would have won more benchmarks against the E8200."

The consider the X3 720 to be a direct competitor to the E8200 (2.66ghz) and not the E8400.

Despite the extra core, I still think E8400 is the superior CPU.

^ how? I agree that he only needs to add some ram but the P2 is better than the E8400 because the extra core stops the AV, OS, background programs, etc from disrupting gameplay since most games now use two or more cores, with the latter being more likely with current releases/patches.

There really is no point upgrading to a Phenom II x3 if he currently has an E8400.

He'd have to upgrade to a top of the line PII x4 or an i7 to see any noticeable difference considering
how powerful the E8400 still is. Furthermore, since he has a 775 socket, he might as well just upgrade
to a Q9550, which has dropped by almost a hundred dollars to $210 (at newegg, or $180 at microcenter)

The Q9550 currently matches the fastest PIIs out there.

should I consider getting a new motherboard?

it makes no sense getting a 4850 x2 to replace a 4850, unless ur board only has 1 pcie connector, but if it supports cf then kust get another 4850, id stack with the e8400, u wont see a big difference in perf unless u use apps optimised for multi cores, or as BSOD said (if ur board supports it) just get a quad, but upgrading the ram and gcard would be the cheapest way to a noticeable perf increase now.

This sounds like a "should I get i7 vs anything else thread". For MT, the 720 wins, otherwise, its a tie. Although, the upgrade option is there for the P2 system

For new builds, I'd say the X3 is the way to go, but to spend all that money on a sideways upgrade is worthless. The X3 720 and E8400 are neck and neck, with the E8400 edging it out in single/dual threaded apps and the X3 winning in multithreaded and (likely) future apps. Personally, I'd wait on any upgrade, I don't really see the need. But if you do need, go for a video card/memory/PSU.

I think the E8400 should last a couple more years. I'm not planning on upgrading my E8400 yet as it is still a solid performer in games, especially when overclocked. I wouldn't spend my money on a new motherboard just to get a PhII X3 720, as what has already been mentioned here, you won't really see any performance gains.

For now, if you don't see too much of a need to upgrade, I would personally wait until the next generation of graphics cards come out at the end of this year and see how they do, or if at least there are any price drops with the current generation. Then if all is well, do a graphics card and PSU upgrade then. At least you could take those with you to your next build. You could possibly upgrade the RAM for the time being, but again it depends if you need any more memory.

For what do you use your computer? In particular do you use apps and games that benefit from multi-threading? Do you multi-task? Some details would be helpful.

You would get the most value for money by upgradeing your graphics card to a 4870 or 4890; or adding another 4850.

Changing your cpu is a total waste of money the only thing that makes a difference in video games is the gpu the only reason you upgrade the cpu is to remove the cpu bottleneck on the gpu. If you leave you e8400 at default clocks it will create a bottleneck, so i would overclock it to 3.8 ghz+ which isnt very hard with that cpu. You should see some performance increases with the gpu you currently have. If you aren't in a huge rush to upgrade i would wait untill the new 5000 and 300 series come out from ati and nvidia that will make your computer the most future proof for playing games. If you need to upgrade now(if i was you i wouldn't i have a similar system performance wise) get the 4890 and overclock it. http://www.anandtech.com/video/showdoc.aspx?i=3539&p=18 thats the review on the 4890.as you can see it 3 times faster than the video card you currently have.

for him this is the case an e8400(when overclocked) will keep up with the fastest cpus when playing games, where as not all gpu's are going to yield equivalent performance i was giving him information useful for his build and just because i made a account the other day doesnt mean i have no idea what im talking about and i dont believe their is a huge difference between newbie and wannabe. Bottom line is upgrade your cpu will do nothing for game performance and upgrading you gpu will make a world or difference (this again is about this persons specific questions which i am giving my input on) and only was a poor choice of words i should have said main

Owww....

Today I learned something valuable.... I like grammar.

But yes, stick with your current motherboard/cpu, there's no good reason to upgrade those. Going to 4Gb of memory might be nice, and as for a new GPU, I'd wait until the HD 5000 series from ATI or the GTX300's from nVidia (or both.)

Who needs grammar just spit it out to a voice recognition program.
