I'm building my first ever gaming rig. It supports DDR2 800 and my question was... Should I get 8GB's (4x2GB) of DDR2 apposed to 4GB's (2x2GB) The reason why I ask this is becuase DDR2 is at its peak cheapest at the moment, and slowly rising, so I want to grab a bargain now, rather then paying more in the future.
The question is would I ever really need more then 4GB's of RAM for gaming? (not 10 years down the line, more or less around 2 years. Would 4GB's ever be needed?) I'm on a strick bugdet, and really don't want to overkill my wallet for nothing.
Like o1die and treefrog07 wrote, 4GB in a 2x2 configuration should suffice for most activities nowadays.
I think it must be mentioned also, that you would have a small performance penalty just for populating all slots, although you should not notice it; especially when using smaller capacity modules (like in a 4x1 configuration). Only when benchmarking.
However, unless it is required to max out the motherboard capacity; it is a good practice when building any type of machine, not just a gaming rig, to live two slots free (or three in a triple channel build) for safekeeping in case they are needed in the future.
