i was just wondering if ill notice a difference in gaming and everyday use cause the single stick is like 20 bucks cheaper
Always go with the single stick over dual-sticks if you can. It will leave you room to upgrade, and it actually is a bit faster. Having all the ram in one place is easier for the computer to read than having several sticks of a smaller capacity.
Get 2x4 gb because then it will run in dual channel mode and will be faster
but is it gonna be noticebly better for the 20 dollars more that i have to pay
