No matter how much research i did it all came down to whats currently available, i wanted a 3850 but could'nt find one for sale unless i got it via ebay, then theres the worry of ending up with a dud! (See Below***) so im going for a HIS HD 4670 IceQ Native HDMI 1GB (128bit) DDR3 AGP £100 inc post and no matter how many forums and reviews i read, actual gameplay videos on youtube did it for me, more importantly if someones running AGP game rig then they'll be upgrading for brute force dx9 peformance
with a 4670 i can hang on to a great p4 based rig while i consider a whole nother beast when price vs power is golden leaving my pockets fuller for now while i rip through 50 - 100 games inc classics like fear quake 3 ut2004 bioshock etc at blazing framerates and still having decent performance fun with crysis ut3 gow
PS the only 3850's i found available are sapphires and i heard they are a bit of trouble where the HIS 4670 has mature drivers now and with less pwr consumption and quiet fan i guess that says it all
PPS there are 3850 powercolors out there but its a hassle bidding and u still could get a dud with low if no guarantee etc,
anyway glad i can get my rig up and running with kickass replacement over the BFG 7800gs OC
as the worst thing is having a top rig for its time that you wanna hold on to and having to settle for a pisspoor gfx card
*** BFG 7800gs OC halted after a year (second hand purchase C.E.X!!!)
in fact the only PC tec ive ever bought second hand was that card tut tut
