The 6450 is about twice as fast as the 5450 IIRC. If pricing is similar and those two are your only options, then I'd get a 6450 unless a 5450 is already good enough for you. What do you intend to do with this computer?

The 5450 is about 1 year old and could be had for a round $30 here in the U.S. The 6450 is around 6 months old and about $5 more and you get 50% more power at the same electrical use. Unless you already have the 5450 on hand I can see no good reason to choose the 5450 over the 6450.

I love games but not a hardcore gamer, i need card which can run most of games minimum at medium settings for my 1368x768 resolution

The 6450 might manage that, but I think that at least some modern games might be a little too intensive for that and would take something more like a Radeon 6670.

Also, bucknutty, your time frames are off. The 5450 launched in early February of 2010 and the 6450 was in February of 2011. That's about two and a half years for the 5450 and about one and a half years for the 6450. I'm also sure that the 6450 has much more than a 50% performance advantage over the 5450.

Wow... time flies, come to think of I was thinking of when I got my cards, not when they came out.

Although the 6450 has 160 stream processors when compared to the 5450 that only has 80 it is not quite twice as fast because they both use the same ddr3 ram. They have the same amount of texture units and rops.

On a side note the 6450 is supposed to be available with DDR5 which would really speed things up however I have never seen one.

I have 2 HTPC. Both are identical e8400s with 2 gigs of 800 mhz ram. One has a 5450 that I got about a year ago. That system got a 3dmark 06 rating of around 6,000. About 6 months ago I got a 6450 for the second htpc and that system gets around 9,000 in 3dmark 06.

I know it’s one synth but I that was about a 50%. Either way at around $30 both cards are impressive when compared to my much older but much more expensive 9800gt low profile that gets around 11,000.

I used 3dmark 06 only because those htpc are still on xp and I am too lazy to reinstall with win 7.

I do agree however if there is gaming to be done the 6450 might be a little disappointing. You might want to spend a bit more and get something with more power. I use mine for the occasional MW3 game on medium-ish settings with aa off at 1920x1080. It gets ok frames, like around 50-60.

I've seen a lot of 6450s with GDDR5 (it's not DDR5; there's not yet such a thing as that in the industry and there probably won't be until between the years 2018 and 2021 or thereabouts) memory and yes, they are what I was referring to because as you said, the DDR3 versions' weak memory interface holds back the more powerful GPU.
