Re: Upgrading my computer
Yeah, the RAM type you need to get is 184-pin, unbuffered, PC3200, at least 1GB, and preferrably a CAS latency of 2. Also, like I said, a processor upgrade would help too. You could do just the RAM; that may get the job done. But if you want to get everything at once, try to find a similar product to the one I said: the AMD Athlon 64 3400+ 754-pin Newcastle. This MUST be 754-pin, not 939, because if it's not it won't fit into your socket. Go for any Athlon 64 754-pin if you can't find the 3400+ Newcastle; should be a much better performance increase from your Sempron. If you can't find out whether it's 754-pin or not, ask us, or simply don't buy it.
That should get the job done, doesn't look like your router would be a problem at all. Like I said, if you want to save $$$ (or £££, whatever), then you can just get some RAM at the moment. Your processor shouldn't be a huge bottleneck. But in the case that it is, you'll need something similar to what I suggested.
ASUS A8N32 SLI-Deluxe, AMD Athlon X2 3800+ @ 2.8GHz, eVGA 8800GTS 320MB, 2GB Corsair XMS DDR400, 160GB WD HDD + 320GB Seagate Barracuda 7200.10, AC Freezer 64 Pro, 700W OCZ GameXStream, NZXT Zero :D
I think I've decided to leave... maybe I'll come back sometime.
