So, I want to upgrade my integrated graphics to a decent graphics card. I'm not a hardcore gamer or high graphics enthusiastic, but I like having medium/high graphics and 20+ framerates. I will play at 1024x768 or 1280x1024 or similar resolution on a 18.5in display. I LIVE IN ALBANIA AND CAN'T PURCHASE ONLINE so I'm stuck with two cards: nVidia GeForce 9500GT 512MB DDR3($70) or Ati Radeon HD 4670 1GB DDR3($110). Do you think the 4670 is worth $40 more, cuz I'm kinda low on budget? My current rig is: AMD Athlon 7750 @ 3.0GHz//ASUS M2N68-AM SE2//APACER 2GB PC-6400 RAM. Please note that I have an unbranded 300W power supply with only 14 amps on the 12V rail, and I can't upgrade right now.
I second the HD4670 as by far the best card. 14 amps on the 12V rail seems really low for a 300 watt power supply though. Are you sure you do not have two rails that could give a higher combined amp rating than that??
I have a generic 300 watt power supply also, but it has a combined rating of 20 amps on the 12 volt rail. I have run an HD4650 and even a low power 9800GT on that power supply without problems so far.
If you only have 14 amps total on the 12 volt rail though, you are, as the shadow187 stated, borderline for the 4670 I would think.
Can't find your answer ? Ask !
I just picked up a 4670 and the box specifications call for a power supply with 26A at 12V. That rating must be allowing for a fully loaded, robust system otherwise, but it did give me an excuse to upgrade my power supply before even plugging it in. I think the 250W (max) supply I removed indicated only 14 or 16A at 12V so I didn't want to risk it.
