Can i upgrade to a GTX 580?

Hey everyone, i have a question i hope you can help with.

Its my birthday next month, and im considering using the money im gonna get to upgrade my graphics card to a GTX 580. However im not quite sure if my computer can handle it. Im mainly thinking about the power supply, but also the motherboard. My current specs:

CPU: Intel i7 860 (SOCKET 1156), 4x2.8ghz
GPU: Radeon 5870, made by XFX
Motherboard: GIGABYTE P55M-UD2
RAM: 4GB DDR3 1333MHZ RAM, KINGSTON
Power Supply: Energon EPS-750W

I also have a dvd drive, 2 HDD's and 3 fans. Not quite sure on the exact models of those.
Any help would be appreciated.

I'm going to assume you know that you need to remove your existing ATI video card. Yes, you can run a GTX580 on that system. However there are some issues to consider.

1) You will notice only very slight performance increase.
2) Your power supply is not trustworthy. The OEM of that model is actually a company called Andertek and they are not known for quality.

Here is a discussion concerning your power supply:

I agree completely with the comments stated above. Overclock your cpu first ( if your cooler can handle it ((don't use the stock cooler!)) ) Try to get a better quality power supply and possibly a higher wattage like 800+ to compensate for OC's and the 580's massive power consumption. At this point, you should be good to go. If you do end up upgrading your gpu, I would be more than happy to buy your current 5870, for a reasonable price.

We haven't been saying that the GTX 580 is not more powerful than the HD 5870. We have been saying that on his system he will only notice a slight performance increase. This distinction is obviously too subtle for some participating in this discussion.

The performance increase also varies from application to application (which is not reflected in the 'non-cited' benchmarks above). He might see an increase of five frames in one game, three frames in another game, and no increase in yet another.

There is already a consensus in this discussion that the power supply is the thing he needs to focus on first.

Well, what is your budget? Don't forget about OCing your cpu...it will help. Have you a after market cooler?

Something like this would serve you a long time ===> Corair

krol146:
Your PSU has a combined 72 amps on the 12 volt rails (18A x 4) on a 750 watt unit. People are trying to say that you need a new PSU and that your Core i7 system is not powerful enough to get much of a boost from the upgrade. I hope you are seeking opinions in other forums instead of just this one.

Um... an i7 860 isn't going to bottleneck much if at all - not below 60fps anyway.

OP: Your system can run it but like it's said, a PSU upgrade might be a good idea. A 750W PSU is enough per se, but only 20A per rail is kind of weak - although it does matter just what is connected to which rails. If the GPU is working from 2 rails then you should be ok in that regard.

As stated, the 580 isn't really much of an upgrade and IMO not worth the cost at all. It's too bad you find yourself having driver issues, I guess I'm lucky in that regard as I've had very few issues overall. I would have suggested you just get a second 5870 but I guess that's not something you want to do.

That tends to make the ATI fans mad when people say this.

Corsair = Good

It is not a waste of money to avoid destroying the components of a computer. It avoids wasting money.

The Mars 2 is kind of interesting with two GTX 580 GPUs. The single GTX 580 Mars though is only clocked at 816 mhz with 1.5 gb RAM, versus the MSI Lightning Extreme at 832 mhz and 3gb of RAM and the Gigabyte SOC clocked at 855 mhz. These are all pretty expensive cards.
