Guyz,
Thanks a lot for ur support. If u see my profile I intended to buy gfx long time ago, but hold it back for heat issue (I discussed this in many forums but found no solution) also needed not much that card than. Now after so much time nothing happened to my rig, rig is also lagging I thought to give just a try.
I could not solve heat issue even using various methods.
Infrared temp gun also reported all components under 50 c, however that is superficial temp and fan on condition, which is not reliable. However BIOS tells different story, around 75 c cpu and mobo and this software image - *img801.imageshack.us/i/hitemp.png/
Main Applications are -
Artcam Express 2011 (require fully open GL 2.0 comliant card), Adobe Illustrator, Photoshop and Vector Magic. And some free time Gaming too
My rig is Intel DG31PR (bad choice, I know), Q6600, 320 gb sata Hitachi, 80 gb ide seagate baracuda, FDD, samsung syncmaster 753s (upgrading in near future), CM P+ 500w, Transcend 2+2 gb 800fsb, soony DVD-R, Canon Lide scanner, Logitech webcam.
Heat solutions- reapplied Tuniq TX2 on all parts, generic HS on cpu (like Kartikoli said using CM212, I confused it with CM psu while chatting), HS on south bridge, small fan on NB HS, HS covers on Ram+ small fan, two 92 mm case fans, cabinet is tower.
I especially thank Kartikoli for his support and that he does not seem eager selling his card, instead he kindly helped me sort out my problem.
I know I need upgrade badly, but that is at leat a year away, till than I need a gfx.
So seeing all these conditions, contestant are 4850, 5670 and 9800 green.
Thanks all for taking ur time and valuable comments.
Hope to sort out this with ur help.
