i really dont know much about computers but with my new pc which a friend made for me, one of the biggest upgrades was to put in more RAM an it made such a huge difference, though you may wanna check with people who really know what theyre talkin about to give you their insight first :P

cheers for the help :)

upgrading memory (or other hardware) on a mac isn't as easy as it seems, especially on the older models. i recommend that you do a google search on how to add more memory for your candy coated macbook and use the right tools for the job also.

I'm by no means an expert, but I have been working with computers for quite some time. Also, I'm a PC guy who builds his own computers (haven't bought a prefab box in over a decade), but I do have some passing familiarity with macs.

Really, the answer to your question depends on the nature of the performance issues you're having.

If it's a latency issue, the RAM will not help; no hardware upgrades will (with the possible exception of the Killer NIC... and probably not even that).

If you're having frame stuttering issues, RAM *might* help. Do a little experiment; does it get worse when you run other programs (itunes, safari etc..)? If it gets worse, then the RAM will probably smooth things out. Conversely, if you're running these as well as WoW normally, then try shutting them off and seeing if things get better.

If the above doesn't seem to have a noticeable effect on your performance issues, then your bottleneck is either the processor or the video card. I wouldn't bother trying to upgrade your processor; especially on a mac. Upgrading the video card however, might be possible depending on your setup.

From what I've seen recently, 90% of the performance problems that people are having are due to running their display settings too high on sub-par video hardware. Video cards really are not that expensive (for instance, an ATi Radeon 4770 costs about as much as a RAM upgrade) and will provide an enormous boost in performance compared to onboard video. My bet is the video card is what's holding you back. (As a side rant, this is one of my continuing grudges against Apple; the stock video cards are usually 2 generations behind the competition).

TL;DR - RAM? maybe, but the video card is a more likely culprit.

As an additional note concerning video cards; depending on your motherboard, it may not be worth upgrading. Depending on the age of the motherboard, it may have one of two types of slots for the video card; either an AGP, or a PCI-X.

AGP is functionally a dead standard; it's still around but nobody makes decent video cards for it anymore. If you have an AGP slot, you're better off saving up for a new system. The upgrade really isn't likely to be worthwhile.

If it's a PCI-X slot, then yeah, go ahead and upgrade. Personally, I prefer nvidia cards, but right now the Radeon 4770 is a great deal.

I use newegg.com for 90% of my computer parts purchases; highly recommend them.

Of course, all this really depends on your financial situation, your current hardware, the kinds of systems your friends are running (and how soon they plan on upgrading) etc... Please don't take what I'm saying as gospel; there are plenty of exceptions all around. I'm just trying to provide some guidelines.

Yeh it does run noticeably worse when i did experiment and it only stutters when i'm in cities and it has to load numerous models of armor, weapons and mounts. Outside of them its better . I would upgrade my video card but since its an imac i have limited room and cracking it open would void my warranty. Cheers Jurm

And com5 there's a grill at the bottom of the unit i just unscrew it and swap out the RAM chip i'm not sure but i'd say its easier and quicker than a PC.
