Hey, that is a pretty good computer, especially for the price. The latest tech like 64-bit and hyper this or that does not make your good computer obsolete. If you are a gamer, your computer came with integrated graphics (Via KM 400A), however, you do have an AGP 8x slot and can get 'wild' with a video card.
Checking HP (Compaq) you can only go to a maximum allowed of 1GB on RAM, 2 sticks of 512MB DDR1-333 2700MB SDRAM.
One of my computers is 6 years old and still runs & plays most all games except the latest high tech ones.
My retired sister was given an old computer (233Mhz) that must be 7-8 years old and she is very happy with it surfing the net & playing card games.
Be happy, your's should last that long.
Alright I know this might sound like a dumb question but I thought I would ask.
Alright I have a COMPAQ Presario SR1215CL. The specs are:
AMD Sempron 3000+
2.00 GHz, 512MB RAM
120GB Harddrive
CD-RW/DVD ROM
Windows XP Home
17inch FLAT CRT Moniter
I got this computer for christmas and I was curious with all the new technology that will probably be coming out in the near future should I trade this in when it comes time that this is a couple of months from being out of date or should I use it till its about dead lol. I mean I paid 650.99 plus tax on this at Christmas of 2004. This computer is really running great. Also, another soultion is just upgrading, the RAM can be upgraded to 2GB I think.
so should I keep till its dead, or trade it in early?
