Hello,
I have a retail bigbox HP desktop, (model # A6600F) which has the Nvidia 7100 on-board. I have been having some latency issue with it playing full HD videos and I'm looking to replace it.

The case size does limit my options but I am more restricted by my price and availability selection.

I have to buy it from Bestbuy and it has to be under $80. I am not expecting miracles from this system but I know a decent Graphics card and memory can go a long way.

I am maxed out at 4gb of ram but have no other upgrades except a wireless card.

This system is used for web surfing & editing my 720p/60fps HD videos for my youtube channel. (I am no pro videographer.)

Some models I'm looking at are:

XFX - ATI Radeon HD 4350 1GB DDR2 PCI Express Graphics Card
Model: HD-435X-ZAH2 | SKU: 9647906

Asus - NVIDIA GeForce 8400 GS 512MB DDR2 PCI Express Graphics Card
Model: EN8400GSSLNTBBY | SKU: 9652935

Sapphire - ATI Radeon HD 4350 512MB DDR2 PCI Express Graphics Card
Model: 100264hdmi | SKU: 9972065
(I like the Sapphire because it has HDMI but I don't know why/how I would really use/need it?)


edit: I will of course, also be upgrading the power supply to a minimum of 400w.
