Transfer rate vs IOPS for gaming

[27POP27]

My current HDD is slow and is very likely causing stuttering and hangups. I've heard an SSD will reduce stuttering and in best cases improve FPS (and lower load-speed ofc).
So here I am as an Intel fan, wondering if their low random read/write will be noticably outmatched by an Kingston SSD with 3x faster random read, when it comes to actually noticing the difference in loadtimes and stuttering.
Is Intel more expensive and slower in this manner because they outweight Kingston's SSD in other fields? Does their higher transfer rate actually make a noticable difference compared to Kingston's SSD, which has the advantage in IOPS?

INTEL 520 SERIES 2.5" 120GB SSD:
Transfer (read): 550 MB/s
Transfer (write): 500 MB/s
Random read 4KB: 25000
Random write 4KB: 40000
Price: 167.15$ (in my country)

KINGSTON SSDNOW V300 120GB SSD:
Transfer (read): 450 MB/s
Transfer (write): 450 MB/s
Random read 4KB: 85000
Random write 4KB: 55000
Price: 120.00$ (in my country)

IOPS are most important, read more then write. Usually maximum throughput is important when you copy files, but it is hard to find a target which is fast enough to deliver or receive so much data. It is possible to feel the difference, but for your usual gaming workload the difference will be not so significant.
I would suggest the Intel 520 or a Samsung 840 Pro, both drives are fast and reliable and have 5 years warranty.

SSDs do not improve FPS; only upgrading your graphics card will do that.
SSDs only improve game-load and level-load times.

Intel is more expensive because of their brand name (like Apple).
It is also more expensive because of reliability. Intel spends more money validating the firmware of their SSDs before they release them for sale.
The longer you validate and test, the less need for firmware updates after the drive is released.

Of the 2 drives you listed the Kinston has better IOPS and will perform better when used for gaming.

I'd chose both answers as "solution", as both are helpful, but conserning Dereck47's reply, I'm not entirely convinced with the statement: "SSDs only improve game-load and level-load times." I am sure I've read that slow HDDs can cause small hiccups and minor stutters, because of the low random read/write rate, and it also makes kind of sense to me.
