Pentium 4 Bottleneck

post #1 of 35
Thread Starter 
I was helping my friend with an upgrade so he could play games at more than 10 FPS. So we upgraded the motherboard so he has a PCI-E x16 slot. He bought a HD 5750 and when I ran League of Legends on it, it was stuttering at 20 FPS and it stayed at 20 - 30 FPS no matter what settings they were at.

The specs are:
Intel Pentium 4 516 @ 2.93 GHz
Gigabyte G41M-ES2L
2 x 1 GB DDR2 - Not sure about brand or frequency.
230w Power Supply - Came from an old HP desktop.
Sapphire ATI Radeon HD 5750 1 GB

If it's a CPU bottleneck, could he just buy a E5400 to fix that?

Help is appreciated!

As sure as there is a sky
Maybe better psu I really don't think anything on p4 level is good for gaming anymore I had a phenom x4 and I did not believe how much of a bottleneck it was on my gpu

I just upgraded from a Pentium 4 to a E5400. The graphics card is great, but the CPU is definitely the bottleneck!

I can tell you that my E5400 with 2GB RAM and 9800GT plays Bad Company 2 on low settings with 60 FPS!

Also, I don't know how the power supply will hold up... I'm surprised you got that 5750 running on it.

I'm concerned about that powersupply, I have to wonder if its adequately powering everything. Maybe it cant give the GPU all the juice it wants.

Pentium 4s are very slow, even at high clocks, (still slow like snail when i oced pentium d to 4ghz)

anyways, yeah, upgrade the cpu u will see a notable difference

that is true, tho with no overclock intended, and after cpu upgrade it should bring down the voltage some more too, and the VGA card doesn't take that much voltage to operate, it sounds like it should be fine and all

but a small upgrade on psu would be a good idea anyways, sufficient power is a good thing for a PC, i learn it the hard way (nothing broke, but took some risk to figure that out)

get a dual core at the very least, doesnt have to be expensive, in fact I would recommend you bought one cheap or used, because its an outdated platform. I would also recommend a better PSU asap. To answer your question, yes, his CPU is the source of his bottleneck.

An OEM 230w psu is ok for a system without a dedicated GPU, but as soon as you added it, you have already put the system at risk of failure.

A decent 400w PSU will be adequite at powering his system, and I dont recommend going any further with upgrades until you have replaced the PSU.

This.

Obviously if you can nab yourself a cheap core 2 quad then do it.
