Choosing (*replacing) memory (RAM) for my current PC

[El Geo]

I'm planning to change my 2 memory RAM that I already have on my PC.

The memory ram I already have on my PC are 2 Exceleram E30106A of 2GB DDR3. So basically I have 4 GB ram (64-bit OS, Windows 7).

My motherboard is GA-H61M-DS2 that has only 2 slots for memory ram.

Graphics card is AMD Radeon HD 6770 1GB

Processor is Intel (R) i7-2600 CPU @ 3.40GHz , 3.80GHz

I'm planning to buy ram so I can have at least 8 GB. Is it worth to go for 16GB for my computer (is my pc powerful enough to use all the 16GB or will it be a waste of RAM with my current PC) or I won't see a big difference in performance with my current PC? I'm mostly using my PC for gaming, video editing, photoshop etc.

If it's not worth to go for 16GB, should I buy 1 memory ram of 8GB or 2 memory ram of 4 GB so I can enable dual-channel?

Also which brand do you recommend me? Are Corsair still considered the best?

***gaming, video editing, photoshop*** - definitely worth getting 16 GB of RAM and your processor is more than enough to handle it. That's not a weak system yet.

Get G.Skill 2 x 4 GB RAM kit for dual channel. If it doesn't fit your budget/not available at the time of purchase, go for Corsair.

If you have any website to buy RAM from, I can recommend you one now within your budget.
