Help needed, GTX 580, Mhz VS RAM

[drmescaline]

So, hey, I want to buy a new computer, and I'm looking for a good GTX 580, and my question is what is better?

GTX 580 (More Mhz):

Core Clock 855 MHz
Shader Clock 1710 MHz
Memory Clock 4100 MHz
Memory Size 1536 MB
Memory Bus 384 bit

OR

GTX 580 (More RAM):

Core Clock 772 MHz
Shader Clock 1544 MHz
Memory Clock 4008 MHz
Memory 3072 MB
Memory Bus 384 bit

The price is almost the same, the more-mhz cost a bit more (45$)

If the other parts I'm buying are important to that chiose, so click the spoiler

Spoiler

CPU: i7 2600 3.4Ghz
RAM: 16GB Corsair Vengeance White LP 1600mhz (4x4GB)
Motherboard: GIGABYTE Z68XP-UD4
PSU: Antec High Current Gamer 900W Active PFC[/u]

Thanks for those who can help me

Thanks for the quick reply, and I forgot to mention that I'll use my TV, 32 inch (No idea the resolution, new screen)

The 3GB of VRAM will only be usefull at very high resolutions, 1.5GB will be fine for 1080 or less. Then again you can always overclock the 3GB version to match the 1.5GB clock speeds.

Thank you very much, I think I take the 1.5GB for now, and in the future, SLI with the 3GB, but I'm not sure, anybody else got an opinion on the subject..?

 

[Gothams Finest]

Not sure if I have misunderstood your last post or not, but if your planning on getting the 1.5GB now and a second one later on to get a total off 3GB it doesn't work like that. VRAM does not stack.

Wow, stupid me, I meant, I will take the 1.5GB now, and SLI the future,
or it's better to take the 3GB and SLI it in the future, I know the vRAM isn't going to stack, that's why I'm asking....

IMHO I would get the 3GB version and overclock it.

If the card with more ram costs $45 less, it's a no brainer to go for that one. You can OC it to be within a negligible difference of the more mhz one, and thus get a card just as fast with twice the memory for less money.

This would also be a superior option if you do SLI it in the future, with all that horsepower might as well eliminate the risk of becoming memory-throttled in next-gen games. That's not a big risk, but nonetheless.

Thanks, when you say it like that, I think I'll take the 3GB and overclock it a bit, because I'm not a fan of overclocking...
