First of all, I am not an expert on gaming. Still, there's something I want to mention to you that you will be aware of. Unless you're building a lightweight ultra book computer with minimum weight, you need to think about adding a hard disk drive to your stuff.
Yes, the SSD is the way to go for top performance. No question. But you can improve performance and the ease of operation by adding a hard disk drive. The hard disk drive for backup. It reduces some of the load of the SSD for tasks that do not require high-speed access. Namely, the video archives and backup sets and ordinary Word documents and spreadsheets. The high-speed of the SSD is very useful work with low time and for quick response in playing some games.
And no, I don't hate SSD. I have had years of experience working with hard disk drives and understand the trade-offs between using the low performance high-capacity hard disk drive.
You need backup copies of some your installation software and your operating system and some other utilities and things that do not have to be loaded at boot time. That's what hard drives are for.
And that is not just my opinion. This is the same answer, you'll get from other people who have had more experience and will tell you that, unless you want a lightweight, portable computer, you still need the hard disk drive for backup and storage of stuff that does not have to be loaded at boot time.
So please think about getting a hard drive, even a cheap old grubby hard drive that has anywhere from 250 GB to 500 GB of extra storage.
That's all I have to say. Bye.
