Venkat sir,
Thanks for sharing the link for tomshardware.com it really has a lot of good information on the Graphic cards.
I did some reading on the site and based on their analysis and my budget have shortlisted below two Graphics Cards
1) Sapphire AIT Radeon HD 5570 - comes for 55$ or 2475 INR
2) Sapphire ATI Radeon HD 5770 - comes for 103$ or 4635 INR
On Tomshardware while reading the reviews etc I found below link that has comparison of a few GCs including the above two for the HTPC usage.
The Kings of Multimedia Playback: Contemporary HTPC Graphics Cards Reviewed. Page 9 - X-bit labs
Now the 5770 and 5570 both seem good to me :
5770 consumes more power than 5570, requires bigger heat sink and hence makes it more noise (around 5 times noisier ) thus 5570 seems better here
5770 seems faster at processing than 5570 - however I think this becomes important for gaming but for HTPC both should be good.
5770 seems to have better picture quality than 5570.
My questions are :
1) For movies / HTPC in your opinion will 5570's picture quality be good enough or there will be noticeable difference between 5570 and 5770
2) If the answer for above is yes then does the PQ difference justify the price difference between the two cards ( price diff is approx 2200 INR)
3) I read in one of the post by you that your HTPC has 5770 - Do you experience any noice or heat problem while watching movies?
Thanks for your help in advance.
Regards,
Naren
