Both range from 110-170-4 a GB of memory . You also need to know if your case is micro-tower,mid-tower,or a full ATX case. MINI'Micro" towers are not gamming CASES so it is very unlikely to fit. Mid towers and Full towers are capable of cooling them-Fiind out on-board video type before you buy one from the link below&make sure of your tower. I recommend you tell me what your Pc is because you have one more thing before you buy"does your PC mobo have AGP slots PCI , PCI Express, or is it PCIE 2.0 Yes all this is needed to be known before you buy what you can not use in you PC maninblack4r@yahoo.com
