The IOPS is only something that you may use a lot if you are doing word processing ar some other buisness oriented operations. For gaming you are not going to be needing a "Max IOPS SSD". You would just get a good fast read/write performance SSD.
You will not notice any difference unless you are running a highly complicated professional, financial, or scientific application.
Over on the business enterprise side IOPS are measured to determined storage requirements for a server -what type and how many data storage drives are required to keep a network running efficiently. Unfortunately OCZ marketing does not mention that. Instead OCZ advertising totally abused the benchmark and mislead gamers and enthusiasts into thinking more is better.
