both processors are dual core and only a 0.2 Ghz difference in speed.
the motherboard is an UEFI type BIOS. You wanting that?
You would get USB3 compared to USB2
both motherboards use DDR3 RAM, you could up your current to 8GB if wanted
you gain onboard HDMI, only good if you have an HDMI monitor/TV, but you already have HDMI from the video card.
My suggestion is new video card, an SSD drive, added RAM and call it a day, saving money too.
Alright then, this is my present conf:
Asus M4A78LT-M LE
Athlon II X2 250
1TB Seagate Barracuda ST1000DM003
Transcend RAM 3GB DDR3
Sapphire HD5670 1GB DDR5
Fractal Design Core 1000
Chieftec 400W
I like my case and I'd like to keep it and fit something stronger in there.Something that would serve mainly non-gaming purposes - playing movies, some web development, some statistical analysis and a bit of Photoshop. I'm looking for something:
1) Quiet enough,
2) Fast enough and within my limited budget.
So, my thoughts are following:
1) Sell Athlon, my current Asus MB and RAM for around (hopefully) $70
2) Get Asus Z97M-PLUS (around $140), Pentium G3258 (around $80), 2 X DDR3 4GB 1600MHz Kingston HyperX (around $90) and SSD M.2 SATA3 120GB Kingston 550/520MB/s (around $100) or SAMSUNG SSD 840 EVO 120GB (around $85) and keep the rest of the configuration.
Why Z97M and Pentium G3258? I think that this CPU would be sufficient for my current needs, and if I'm not mistaken the MB should be relatively "future proof" investment for if I decide to get an i5 or Intel gen5 CPU later on. For SSD, I'm not sure if M.2 is worth investing that extra $15. I'm planning to split the SSD in two partitions and run dual boot with Windows 8 and Linux Debian, which I'm currently using as my primary OS. I'd keep 1TB Barracuda for storage sake.
So, to be as specific as possible - my questions are following:
1) In general, am I on the right track? Is this configuration going to be a good value for the money and are there better alternatives for what I have in mind?
2) Should I get that M.2 Kingston SSD or a regular one (like Samsung 840 EVO e.g.)?
3) Do I need a new, stronger PSU right now or could I leave that for later on?
Thank you for your feedback, any help is appreciated.
