PC started out with 2 gigs and about 2 years ago I added another gig. Has 3GB now on it and I'm limited to 4GB Ram on my mobo.
My PC is using DDR2 memory so that is not usable I think or maybe I'm wrong? Anyways, I won't have any use for 3X1GB memory sticks. I, at least want to go 16GB RAM. I think that getting a true octacore will have me running for at least 6-7 years. Current rig is going into 9th year. On year 7-8, I noticed how slow it has gotten (relatively speaking)
I agree. Did that too in December (SSD was going to be used with new build). PC is fast to load apps/windows but that's about it. You can feel how sluggish that e6600 is. Rendering image heavy forums/threads etc basically makes the PC crawl at times. Doing video editing is a chore. Video encoding/transcoding is slow but livable if done as an overnight job.
An incremental upgrade every ~3 years, will get you more performance down the road and will be much less costly in the long run, than going all out and stretching it for 8 years.
A reasonable thing to do right now, is buy a Z97, i7-4790k, 16GB DDR3 for approx. $100/$340/$125 = $565
A bit extreme, would be to buy X99, i7-5820K, 16GB DDR4 for $200/$400/$170 = $770
It's your money, but I know what I would do...
