@ Joncnunn, yeah you Cpu Clock Speed is 3.4Ghz when doing comparisons because that is what your Cpu will do when required. I know laptops generally have larger variations between "economy" and "power" because they are harder to keep cool and quiet. Your Laptop will be fine, if not amazing at Civ6
@Sadsquid, I have the same card in my work machine.. It has 2GB Dedicated Graphics memory and can use up to 8GB of Shared Memory. Pretty sure you will be fine, although when dealing with Graphics Cards , Video memory is the least of your Concerns. My GTX680OC is older but it is a lot faster than my GTX750Ti ranking 33/522 VS 83/522 even though the Core Speed and memory Speed and size is the same. That GTX750 is an excellent budget card though
and will be fine, but not amazing. at Civ6(i doubt it will do 1080p at Max settings
)
Use this to bench your card if you like peoples

just pick your card or test your GPU, if you are browsing on the same machine. Anything in the top 150 will be fine...watch out Laptop users,your cards are significantly slower than the desktop versions.
One thing though when doing laptop conversions is to take into consideration that they are different than desktop CPU's, even if they have the same Clocks speed and designation. an I5 in a laptop will not be as powerful as an equivalent i5 in a desktop. generally they have less logical Cores and smaller Cache size. The smaller cache size is generally the important one, though newer games are starting to effectively utilise more logical cores.
On this note, more Cores dont necessarily translate to more power gains. The software needs to be written with respect to this to actually make use of the extra cores effectively. As a general rule i5's are just as quick as i7's with respect to games, assuming similar clock speed. 4 Logical Cores will generally be enough, but if you are upgrading you should go for 8. (Current i5's have 8)
