New build 4g or 8g RAM?

I am building a backup tower for gaming and it will have
a ASUS P8Z77-V-LK MB and a i5 3570K cpu
I am looking to spend as little as possible for the DDR3 RAM sticks
so does anyone have any suggestions?
should i just go 8g with a really fast speed? or just use 4g?
My main tower has 16g's and i never use all of it,
i just game and watch movies and download
on the tower. many said 8g is plenty for that?

  1. 8GB of RAM is enough.
    You don't need really fast RAM,1600 MHz with a CAS Latency of 9 is enough for anyone. ;)
  2. 8gb of 1866mhz and cl9 is the sweet spot

    Take 8 gigs out of your main computer and put it in your backup computer. That's what I did. It's free. 16 is too much and 4 is too little. 8 is the sweet spot.

    I am new to building and i was not aware i could even do this?
    I have four 4g kingston sticks in my main tower so all i have to do in remove two of those and use it in the backup?
    this is too good to be true! LOL
    My main tower has a ASUS P8Z77 pro MB with a i7 3770K

    Yep, take out 2 sticks and put them in your other PC :)
  6. Are you going to use discrete video card or iGPU from i5 3570k?

    For a second gaming rig I would think it is better to go with a 8GB kit (2 x 4GB), then 4 GB. One reason is that prices might go up now on DDR3 when DDR4 are slowly replacing the market and "older" tech tend to go up in price as production move on to new tech. Second reason would be that 8GB RAM could be considered to be mainstream among gamers of today and most games would be designed to run with at a minimum of 8GB in the near future.

    For speed you only need to have 1600MHz as it is not much you will gain going higher in bandwidth. You can confirm this yourself by looking for Tom's hardwares own benchmark on memory scaling. Save those money to a better video card or SSD instead.
  7. If in the budget I'd get a 2x4GB set for it, prob 1866 or 2133, that way you also have a backup set of DRAM and faster sticks

    yeah a GTX 760 will be the GPU in the back up my main tower has the GTX 780ti
    I am building this in case my main one goes, it will be all ready to just plug in and go until i sort out what happened to my main tower.
    I got the parts really cheap so it was a no brainer to build a back up, i got the case,MB,i5,cooler card reader,dvd drive
    and a 1tb HDD for $190!
