Question

No speed increase going from Sempron 3400+ to i5 2500K?

What piece of the puzzle am I missing? I was expecting a speed increase as far as my OS. Load times are still the same and I really noticed no increase in speed at all. I am assuming it is my older than dirt ATI hd3870 512MB ddr4 gfx card. I do have 8 Gigs of RAM. Then again I also have a 32bit OS so it is only seeing 3 but at the same time I went from 2GB single channel pc3200 to 3GB dual channel PC3-10666 as far as the OS is concerned. I thought I would see some improvement. The memory timing is set to the kit's specs. 9,9,9,24. I really won't have too much extra money at all so which upgrade would you suggest? A 64bit 7 pro or a better GFX card or what else am should I look at? I'll be checking back so any questions are welcome.

No change from a Sempron? Have you tried things like unzipping large files, copying a DVD or running Call of Duty or similar games? There would be a huge difference.

You're definitely bottlenecked by your old Radeon HD 3870 card. Although at 1024x768 that should play things smoothly. Did you perform a fresh install of XP, or a repair installation? Have you run a complete virus/spyware scan recently? It's also possible that your long load times are due to an extremely old/slow hard drive.

Higher-frequency RAM has almost no real-world impact on performance, don't waste money there if you've already got a 1333Mhz kit. And yes in dual channel mode, that report is correct.

GPU upgrade first- at least a Radeon HD 5770/6770 although that's overkill for a 1024x768 monitor. Those cards can play smoothly at 1920x1080.

Sounds like you had an older sempron...changed the mother board, CPU, ram, and kept everything else. bet you didn't change the PSU to something more powerful with the 8 pin 12AUX plug. yes in CPU-Z they show the stock data rate not the double data rate so yes you have to do the calculations yourself so it comes out to 1330 or 1333 RAM .. The 32bit XP MCE is killing you..it was designed for playing video not high end computer work nor will it allow you to use more than 3.25GB of that ram. A 3800 series video card (must be from the old machine) is also killing performance. I have to assume the 80GB hard drive is also from the old machine and is either SATA1 or SATA 2 at best...with low cache the Seagate is also a 3GT/s drive...use a 6GT/s

In all your OS, Video Card, PSU, and to some extent, hard drives are killing performance so you "load time" will be slowed up...If you really want FAST dump the 80GB drive...get a 64GB SSD and just put Windows 7 64 bit on it.
