My computer is an HP p6320f.

I'm down to two cards - HD Radeon 5670 (512) or HD Radeon 5770 (1 GB) : both are GDDR5

Which is the better card to go with? Will both fit into my computer? Is Sapphire reliable?

My PSU needs to be upgraded, too.



Is that PSU reliable? I'm pretty sure it fits my case.

My current PSU is

This purchase will be within the next month. Would you suggest I wait for Black Friday, or Cyber-Monday? Any and all advice is appreciated. I anticipate that the 5770 is the better card.

Thanks

The Cooler Master Elite Power 460W (RS460-PSARJ3-US) is a re-badged version of their 400 Watt model. It can't deliver its labelled 460 Watts of power.

When you attempt to draw more than 400 Watts from that power supply the electrical noise and ripple exceed the maximum allowed on the +12V rail.

You're better off sticking with reputable brands like Antec, Corsair, Enermax, Seasonic and XFX.

PSU is junk. No PFC, not 80+ cert, etc. Wouldn't get that one. The 5770 is a much stronger card.

Alright, 5770 is what I will go with. I asked some other questions that will help me know when to buy this.

This should do the job, for a psu right?

When do I buy these? Black Friday? Cyber Monday? 2nd week of December?

Will the PSU fit in my p6320f case?

No. Avoid the VP-450 Antec as well.

Alright.. won't work, with no further suggestions...

This HAS to do it then! Corsair

That one does fit in my PC. Now, my tower doesn't have many "holes / mesh" in it. Should I drill a few more for better airflow? This is an HP p6320f after all..

Is there a fan in the front of the case which may be covered by the HDD cage at the bottom front of the case? If there isn't and there's room to add one then that would be an option for increasing the air flow through the case.

You can always replace existing case fans with higher air flow rate versions.

No, there isn't. HP for you.. I can look into that (upgrading current fans). Now, the PSU's that have a 120mm fan, do they BLOW air down from where they are seated (my PSU is at the back-top of the tower) or do they suck air in and out the back of the PSU?

The big fan on top/bottom, depending on how you orient the PSU, is an intake fan. Cooling air is drawn in by this large fan and the warm air is exhausted out of the back side where the power switch and AC power receptacle are located.

Alright, that makes sense now. So, do all case fans basically suck air out? I'd say that they do?

Fans mounted in the lower front of the case are oriented to draw cool air into the case.

Fans mounted on the back and maybe even the top of the case are oriented to exhaust warm air out of the case.

This follows the natural convection current tendency of warmed air rises.
