Are you going to upgrade because of ARMA 3?

[Babylonjoke]

Yes, my 4 years 2.50 GHZ quad core is already crying and screaming when I play Arma 2... so yes, I'll buy a new motherboard and a new CPU...I already have a good GPU ati6870 so....just need to rob 500 € from a bank and buy the rest ..

Just ordered a SSD specifically for A:CO and A3 (Currently on a single HDD). Will prolly upgrade from my 580 to 2 or a 680 or 670 depending on how well the A3 alpha runs.

[CarlosTex]

Yes.

CPU: from current Core2 Duo to the upcoming Haswell processor.
RAM: Get four 8GB sticks for RAMDISK.
HD: SSD
GFX: from a radeon 4850 to a 8xxx series or Nvidia 7xx

As soon as this is all available....

[tremanarch]

yes, but i dont know whats more important: 8 cores or a gtx 680...

[-Coulum-]

Yep, upgrading from a core two duo. Gonna wait until the beta at least to upgrade though. I'm going to try and play the alpha on the duo until then.
Also getting and ssd and possibly trackir if I have any money left.

I'll wait till MSI releases GTX 680 Lightning =) I wanted to 580 Lightning in January but it was sold out worldwide. I hope Core i5 2500k will be enough. Ivy Bridge doesn't seem like a way to go according to reviews.

@tremanarch: your question depends on how many cores you already have and their speed, but remember that whole performance includes RAM, OS and sometimes a good set of HDDs
Do you have plenty of RAM and 2 cores CPU above 2.8Ghz???? go for a new GPU if your current GPU really sucks...
Is your CPU a PITA? well, then you know what is needed...
A2 does not require more than 2 cores... but speed matters so above 3.0Ghz would be sweet
On the other hand, A3 requirements are very similar to those from A2 so there wouldn't be so much difference, Ivan Butcha confirmed them for E3 which just started today... and different graphics requirements are not essential...
Anyways, if you have a decent GPU and enough CPU power you could have at least 4GB RAM @1333 GHZ+ on 64 bits OS to let things go -relatively- without bumps at all ... remember that any 32 bits app won't be able to use more than 2048 MB RAM...
At the end of the day, overall performance will depend on your running apps = antivirus, resident programs, running services, TS, steam, etc...
I'm running on AMD 6 cores + NV 460GTX 1GB DDR5 and 12GB RAM @1600Ghz but before I started with 4GB RAM @1600 Ghz and I could notice a difference, specially when creating what's in my signature

I guess I will wait & see how my rig works with A3 before deciding

[Zorg_DK]

I'm planing on upgrading my 5870 card when Arma3 comes out. I'd love to get a better monitor as well eventually.

Arma is the only game, that worth buying a new PC for.
