The SSD is definitely a big deal if you're one to start your computer up a lot. If you let it idle and don't turn it off, it doesn't matter as much. If you're getting something small like 120/128 GB, I wouldn't bother aiming for a high-end brand. I got a Kingston 120 from Amazon during a pricing error (for $25). It's worked perfectly fine for a couple of years or so now. I'd go with a cheaper offering like Kingston short-term. If you go with a higher-end brand, then you might be better-off aiming for a 256- or 512-GB one, something that will last longer. You're supposed to partition 20% of the drive or so for protection. As someone with a 120-GB, I'm sitting under 20 GB now, have for a long time. If you're buying a gaming PC to game, you want something bigger to fit those games on, I imagine.
