here are my computer specs:

HP Pavilion a1510n

AMD Athlon 64 Processer 3800+

2.41 GHz, 1GB of ram

Windows XP Media center edition

Motherboard: Asus A8N-LA



Recently... I added a GPU from the built in Nvidia 6150LE to the Zotac Nvidia Geforce 8600GT

The performance increased, but not by alot... Became laggy at times.

temp on idle is 53-54
temp on High stress maxed out directly at 70

It became a bit laggy for some games so it worries me if i dont have enough power to supply my GPU. I was wondering if my GPU is working at 50% efficiently rite now cuz this doesnt feel ALOT faster than i expected.

currently 300W of power from PSU. Which is the Min for this model. I was thinking about a 400W upgrade.

okay to summarize all of this.
I think my gpu isnt running at 100% because power demands arnt met. Not sure how to check.

Any suggestions are GOOD. =)
Thank you.

Power supply is about the least of your problems. An insufficient PSU will cause lockups/BSODS/reboots/games shutting down. Low frame rates are not a symptom. A single core CPU and that video card are not a big power draw.

I do not know what games you are playing, but your system overall is a bit weak if playing many of the latest. On the whole, your system itself isn't really mismatched. You don't have a glaring deficiency, upgrading either CPU, memory, or videocard by itself won't help you much. Any upgrade of one will be bottlenecked by the others. Sadly Socket 939 CPUs are tough to find new, and expensive.

You can try to maximize what you have, by cleaning up background processes etc to free up CPU and memory, or upgrade everything. Just an opinion.

I'm going to say your lag is going to be coming from the system RAM but also check the video card drivers and you may try using nvidia's Forceware to OC the card if possible. you also didnt mention the amount of RAM on the Video card.

With an 8600 GT, the power requirements for that card are 300W. However, it is always a good idea to have more. Your biggest slowdown is most likely the RAM. According to HP, you can have up to 4GB of DDR 400 memory. You can get it here at Newegg.

By ram we mean your system's ram. You only have 1gb. For gaming with windows xp, you should have at least 2gb of ram, but 3gb or 4gb would be better.

Also, the DDR2 memory on the graphics card is a little slow, the versions with DDR3 memory run faster.

The RAM on your motherboard is different from the video RAM on your graphics card. Also, there are differences between GDDR and standard DDR memory. Currently, there are graphics cards with GDDR2, 3, 4, and 5.

LOL

ok just to tell you guys i know what is gddr and ddr ram is.

My computer has 1gb DDR 400
My GPU has 512mb GDDR2

Well i guess my target is a ram upgrade.

Current configeration is 2 * 256mb DDR 400 on the MB.

Should I buy:
1*1GB DDR 400
or
2*256mb DDR 400 to match?

Btw since DDR had become more expensive, i decided to go with the 2gb ram config for now. Im also on a budget and im going to hold out a few years till entire system upgrade.
*this is my last question

According to the specs at HP, your computer can accommodate up to 4GB of RAM. I suggest getting all four if you can afford it. Two 2 x 1GB kits should work, like Kingston ValueRAM 2GB (2 x 1GB) 184-Pin DDR SDRAM DDR 400 (PC 3200) Dual Channel Kit Desktop Memory. Even if you don't have a 64-bit OS, having almost 3.5GB of RAM will certainly speed things up. If you're on a tight budget, you can purchase one kit now and one later, but DDR 400 is old and being replaced.

Kingston does have a good warranty, as does Newegg. Most of the people reviewing that ValuRAM seem to like it.
