Hello, I am a greenhorn here, but whenever I search for PC advice this site pops up on google. So I am planning an upgrade on my PC which I use for gaming, I have already upgraded the video card and the ram and it has helped for many games. I am now finding that my CPU (and AMD 64 x2 3800+) is almost always below requirments for newer games. I have looked into it, and I know my motherboard will accept up to the 5000+ (which is often the minimum recommended for some newer games I am interested in). This is likely my last upgrade before I buy a new computer, but the previous ones have served me well and I figure I only am risking 40 bucks or so.
My question is this: What other factors do I need to consider beside motherboard compatibility? Can I assume my memory is compatible with the 5000+ if it was with the 3800+? Will the 5000+ run considerably hotter?
I would suggest you just OC the CPU if you can. Though for upgrading you shouldn't worry much about anything other than Motherboard support.
The memory is not an issue, as all AM2 Athlons 64 X2s support the same type pf RAM (DDR2-800).
For the heat issue, it depends on the version of the 5000+ you get (89W Windsor; 65W Windsor and 65W Brisbane)and the version of 3800+ you have (89W or 65W), the 5000+ may or may not run hotter. But in all cases, the existing heatsink should be adequate for either CPU.
Upgrading your several years (i suppose so) old platform is a waste of money. Better get some new 785G mobo and the Athlon X3 445, a sweat budget gaming CPU. The mobo+CPU wouldn't cost you much, but i'm afraid you'll have to buy new RAM again, to DDR3. I suppose you bought DDR2 RAM? What is the GPU you bought?
You should have asked us before you bought the new RAM.
The 1 mb of L2 is nothing if you intend to play modern games. I 've owned the 4850e which is similar to 5000+ and it only gave me problems (bottlenecks)during gaming, eventhough my gpu and ram were more than decent and the cpu was running at 3ghz (9600gt, 4g ddr2 800)
Since you are looking for a used cpu (i guess!! because the 5000+ is off the retail for more than a year), check mobo compatibility (if its not compatible better get a used am2/am2+,ddr2 mobo at 1/2 the price of a new 785g) and get a used Phenom I x3 for a few more money (8650 at least). The extra 512kb L2 and especially the 2mb L3 is a "must have" for gaming cpu.
you are gonna thanking me later
