Ready Boost, will it increase performance on a system with 4 GB of RAM?

[9nines]

I am using Vista Home Premium 64 on a system with 4GB of System Ram. I use teh system mostly for gaming.

A few questions please:

1) Will Ready Boost increase performance if I already have 4 gigabytes of RAM? Noticeable?

2) If it will give a performance boost, should I stick to 2:1 ratio and get a 8 gigabyte USB Flash Drive or would a 4 gigabyte model give the same performance boost?

3) If I leave the USB flash drive in my computer, will Ready Boost be enabled after each re-boot, or will I need to enable it each time I boot into the operating system?

Thansk for help.

1.) The performance gain is near zero with 4Gb of memory
2.) Microsoft recommends that, on the low end, you use a flash drive equivalent in size to the amount of memory installed in your system. On the high side, the flash drive should be no more than 2.5 times as large as your physical memory. There aren't really any consequences to exceeding the 2.5 times the memory limit, but you won't see any real additional performance gain by using a larger flash drive than that. On the low end, Windows won't stop you from using a flash drive that is too small, but by doing so, you will not receive much of a performance boost. Your performance gain depends on the size of the ReadyBoost cache and on the current workload of the system. Generally speaking, the larger the cache and the higher the workload, the greater the performance boost. In contrast, ReadyBoost will provide almost no performance gain on a PC with 4GB of RAM that is being used solely for word processing or Web browsing:

3.) It stays enabled

The greatest gain from using Readyboost is when you have a lower amounts of memory installed shown here:

But with memory prices how they are today, it is almost inexcusable to be below 1gb of total system memory

Thanks. What about for gaming? Seems for web surfing and word processing no gain per those articles but what about gaming?
